Driving up the highway my '03 HSE (petrol of course) began cutting out at highway speed, then completely shut off (engine, not electrical) and let me coast to a stop along the side of the road. It would crank strong, but not start,so I had it towed home.
Read both OBD reader codes and then the RSW All Comms, and saw no engine failures. After sitting for over an hour, I did gno ahead and try to restart, and it started, ran for a few minutes, then after a few short stumbles, shut off again. Again,it would crank strong, but not start again until it sat for a while.
I did have some gas at the fuel rail Schrader valve, but can't say if it was enough pressure.

So I haven't really narrowed it to either ignition or fuel,
But does this sound familiar to anyone or any experience like this that you can share?
Any ideas?
Thanks.

Sudden failure would lead me towards fuel filter or fuel pump. Mechanical failure of a fuel pump or clogged filter would not log a code. If this were ignition related I would expect to at least see some misfire codes as cylinder dropped out or readings were weak. Then again that is just me scratching my... head out here on the deck at the beach. :lol:

Sounds more like a clogged fuel filter. Try the easy fix first! After stalling out, fuel has worked its way through so it can start and run a bit. My 2 cents worth. Good luck, man!

Well, not having time to give it a good look until tonight, I did order a new fuel pump and filter from Rock Auto on Tuesday night. The filter arrived today (quicker than I expected), so I replaced that.
While I had the old one (170k miles on it), and the new one out, I compared the flow, and the old one allowed me to blow through it as easily as the new one... So I guess I could've saved ~$45 on the filter.
But after putting u to the new one in, I played around a little and noticed that as I saw before, it would run fine for a few minutes if it was allowed to set for a while, but then stutter and stall, and not start again unless allowed a little time alone. I also noticed that the longer I let it sit (up to 15 or so minutes), the longer it would run (up to 2-3 minutes) before stalling again.
It seems to me as if there is something maybe restricting not the flow from the pump, but maybe something that restricts the available gas TO the pump. As if the basket that the pump is in is somehow not allowed full access to the fuel tank - as if the pump starts and pumps all the available gas out of the basket, then has to wait until the basket fills with gas again. Then once gas flows back into the basket, the pump has gas t pump again.

I haven't had the pump out yet, so I have no idea what could be restricting the flow of gas TO the pump (into the "reservoir" where the pump sits?) Can any of you that have held this pump assembly (the whole basket) in you hand, or replaced one think of what could do that?

If so, the pump may be fine, just something keeping it from a supply of gas.

What in the tank or pump assembly could restrict access to the pump? Any ideas?

Oh, I forgot to mention that I did isolate it to a fuel problem by checking for pressure at the fuel rail Schrader valve. Whether or not the engine starts coincides with whether or not there's pressure at the rail. And it takes a while for pressure to build-up.

No one on here has ever taken the fuel pump out of their 2003-2005?
Well I went ahead and replaced the pump too. When I did, I cleaned out the screen and residue in the bottom of the basket.
Works fine now... so far after a few miles, anyway.

Thanks Stan, But I don't think you're reading my questions correctly.
Initially I was looking for input from someone who has experienced the same stalling characteristics. Someone who has had this happen then found the reason.

Then when no one responded, I was asking if anyone had held the whole fuel pump assembly in their hand, and had an idea of if something could be restricting fuel supply to the pump.

I found good R&R of the fuel pump in the forum and on You Tube and other forums, so I wasn't looking for help with that.

S I think you missed what I was looking for.
But all the same, thanks for the responses. It's still nice to get some kind of feedback as opposed to complete silence.

I replaced my filter and pump three years ago. Looking at the pump assembly (motor + housing + level sensor), I don't see anything that can restrict the flow INTO the pump. There's just a plastic web-like thing at the inlet of the housing, and that thing will be very unlikely blocked.

Can it be a fuel pump relay problem?

someone has written a how to RnR the pump assembly search should find it
It's called RAVE, nice detailed drawing of both pickups, both level sensors, pump and filter. Further details including a photo of filter access and a drawing of the lines for the external filter assembly.

No fuel at the engine does NOT mean fuel pump. It means you need to further trouble shoot. Disconnect your fuel filter and check for free flow of fuel. If you have free flow of fuel then your pump is fine. If you have limited flow, or no flow then you have an issue in the fuel tank... assuming you have already tested your pump relay.

03, if you changed your pump without test flow or also replacing the filter it may have been wasted funds. It was not for lack of response either. Your claim of "complete silence" is unfounded and quite unfair to the folks trying to point you in the right direction and assist you. You have had a responses everyday except over the holiday weekend.

Thanks Tony - once I got it out I saw what you're talking about. Maybe the "web" that looks like the sieve that' described in the RAVE operation description. That's what it is supposed to do I suppose.

I'm sorry Toadhall, you (toes in the sand and all) and Rover lover quickly pointed me in the right directions and I'm remiss for not mentioning my appreciation. I meant to.
I went the path that Rover Lover suggested - that said, replacement of a fuel filter with 170k miles isn't really a waste of money, just overdue maintenance.
I did refer to RAVE initially, it leaves a bit to be desired on the fuel pump replacement. I found much better guidance on you tube.
The lack of response I was referring to were the specific questions about if anyone knew what could restrict fuel to the pump. Apparently not a place were many have gone before, other that Tony Luan.
Thanks for the help, but it's all TCO'd. I've put a few miles on it since and not a stutter, knock on wood.

Toadhall & Rover Lover- My mistake about the "no response". You two responded with help almost instantaneously, but with advice on what to do, where I was talking about no response to my question to someone who has experienced this same problem.

I wasn't asking what I should replace yet, but you both did have good info. Just no response from someone who has experienced this same problem.
