Running fine and it just stopped

I swear I posted this last night....anyway here we go again.

I had just finished installing my repaired radiator on my 1993 Range Rover LWB. The battery was dead so I put the trickle charger on her. The next day I went out and started her and let her idle. After a 15 minutes or so, I decided to take her for a test drive.

Everything was fine. Ran like I would expect her to. As I came home I guided her around one of the traffic calming devices and as I came out she died. No sputter just dead.

I got out and started looking for problems.

I have spark.
I tested the coil and have a nice strong spark.
I tested the distributor and have spark to the plugs.

I have fuel.
I pulled one of the lines on the fuel rail and have fuel there.

I have air.
I pulled the MAF from the air filter just to make sure I hadn't sucked a rag in the air filter.

I checked all my connectors and reseated them.
On the coil.
On the MAF.
On the temperature coolant sensor.

The last time I drove her I got an Error 17 (throttle position sensor). She still ran and I drove her once more after getting that initial code.

At this point though, she will crank but will not start.

Could the Throttle Position Sensor cause that? I thought I read that on a forum somewhere over the years.

How do I test the Throttle Position Sensor?

The engine turns over. Injectors make the clicking sound.
After talking to my Jaguar friend I'm thinking I may have some very bad gas. Ethanol can be a problem if sitting too long. Water bonds with the alcohol and can make the fuel crap. I'm going to put some good gas in her and see if that fixes it.
He had a very similar issue with his Jag.
When I checked the fuel rail for fuel the petrol that came out didn't overwhelm me with a strong gas smell as it should have.
I'm gonna get some NON-ethanol petrol and see if it makes any difference.
It has to be this or something electrical as I have eliminated just about everything else.
Thanks for the inputs.
I was beginning to wonder if anyone would chime in. Cheers.
I'll come back if I'm successful and let everyone know what it is.
I am getting close to solving this issue. Would any of you believe BAD GAS?
We put 4 gallons of fresh petrol in the tank last night and after a few cranks and some coughing and choking she started. And she ran for a good 15 minutes. Eventually though I'm guessing the tank settled again and I got more bad fuel and we never again got her started.

I'm guessing I'm going to be getting the fuel sorted out on Saturday. I'm not sure if I will drain the tank or just keep adding more until the mixture is combustible.

More later.
Probably not bad gas. In the case of my friends Jag it was definitely bad gas.

I'm thinking something is getting hot and causing a failure. If it is a coil, I'm gonna be pissed. This thing is eating coils. That will be the third one in 10 years! hahaha. I've been there before and thought the spark was pretty good when I tested it.

thanks for the tips, I'll probably replace it.
Also, check the connection from the Ignition Amplifier Module on the side of the distributor. If unplugged or corrosion it will not start/run like poop ;]
I have installed the Amplifier Module relocation kit. I also checked all the plugs.

YOu hear injectors clicking but is the fuel pump running? Hear the hum from the gas tank? Probably a bad pump or bad wiring. Mine was bad wire at th left rear tire where there is a connector
She runs fine if I start her when she is cold. Once she heats up she dies.
Sorry to take so long to get this fixed. I had to finish the semester. Finished last night.

I ordered a cap and rotor and a new coil. I put them on last night and she started up on the first turn of the key.

I left her running in the driveway for an hour with the bonnet down. Got her up to temp. No problems.

I'm surprised by that a little only because I put a coil in within the last 3 years for sure.

Thanks for all the help everyone.
