It could be fuel pump on its way out. Had similar syptoms volts say nothing its the presure test on fuel that would confirm that. Apparrently should never let fuel below 1/4 tank as pump is cooled by the gas. Do not buy cheap after market pump as you will be doing it twice like I did. It could be fuel pump on its way out.

To candctruckin: I agree that is the suspect problem. I do not understand how this happens with the delay in time almost like it just has to cool down. Is PN# 0021539228 the right part number, and will a Standard Motor Products # PC393 work? Your help is greatly appreciated.To candctruckin: I agree that is the suspect problem.

We have replaced everything in the electrical (including ECM), Fuel, and Emissions systems except the fuel pump relay, and the crankshaft sensor. We are leaning to replacing the fuel pump relay, and possibly the fuel shut off valve if it has one. Trouble: Vehicle runs and drives great until it warms up and then it just shuts off with no warning. Wait an hour and a half to two hours and then if will start and run. Then when it warms up it dies. Nothing so far has made a difference.

Is PN# 0021539228 the right part, and will Standard Motor Prouducts PN# PC393 work as well? Can you tell me where it is located. I have two conflicting stories. One says the it is located on the bell housing behind the oil filter (Tech says it is not) and the Tech says it appears to be on the drivers side of the bell housing.

How do you know it is not getting gas? Have you tested for fuel pressure? Does it have spark at the spark plugs? Have you checked for power to the fuel pump? Given that the engine has been replace make sure all the ground wires are attached and tight. I strongly suspect you have a loose ground wire somewhere.
Replaced the fuel and pcm relays, the fuel filter and the fuel pump.?????
Your guessing not testing . Did you do fuel pump pressure an flow testing before replacing those parts . How about fuel pump voltage drop testing ?
Besides it doesn't sound like a fuel pump problem ,sounds like electrical problem or electronic problem . What's missing after it shuts down ? Spark or fuel . Testing an not guessing is the key to finding the problem . Hooking up a factory or professional type scan tool to view engine sensor data parameters an checking to factory spes. 046 Engine Hard to Start or No Start Scan Data for No Start
Any sensor when hot can cause these type problems .
If the pump continued to run after shutting off the car you fuel pump relay was probably staying latched. I would replace the relay as well based on your info. Along with the pump the fuel filter should be replaced too and fuel pressure should be checked. Make sure your ground is good also.
The only way to know for sure is to hook a gauge to the rail and check the fuel pressure when it won't start. Sitting for a few minutes and restarting is normally a sign of a relay or coil cooling off. There should be a EEC relay that powers the dist module and ECM. I know you said you have spark, but it could be something else related. Also, if you have spark at the right time and no fuel pressure, you should be able to use starting fluid to substitute. I don't suppose you have dual tanks and the switching valve is the problem ?
Possibly the coil module under the coil packs gets hot and shorts out because it's on the engine, ( dumb design). I have seen that happen many of times.
just went thru the same think wit a s 430 it was the crank position sensor . 60 bucks at auto zone and it took me 5min. 2 install if u need help feel free to call me 918 808 9706 chris
If this happens every time you start your truck and it shuts off the same each time, you just might have a dirty fuel filter only allowing so much gas pass through until it clogs once again. I once had a chevy van, when I would drive it, would go a few miles and engine would shut down. I would wait 10 or 15 minutes, it would start up and allow me to drive a few more miles then shut down again. I changed the fuel filter, It was fine after that.

i had the same problem itrs your crank position sensor i guarantee it

candctruckin: I agree that could well be the problem. ?Why or how?
