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?
