I have an intermittent stalling issue with my truck. I would start up the car no problem, drive for about five to ten minutes with no issues. Then after that, the engine will just stall with the oil light on, battery light on, and check engine light on. I had an OBDII reader when it stalled and there were no codes.
I would put the car in neutral and start it up again. Engine would start right up. I would be able to drive for sometime ten seconds, sometimes three minutes and it stalls again. Like I mentioned, it never happens at the first couple of minutes. Only after five to ten minutes of driving.
At first I thought it was the alternator but the battery voltage is at 12.4V and with the alternator running, at 14.0V. So I think that is not the issue. I really do not know where to turn to next. Any help would be appreciated.

Find the fuel pump power lead out of the fuel pump relay and attach a test light to it. Drive around and see if the ECM is shutting off the fuel pump.

What happens if you idle it for ten to 20 minutes?

I will check the idle today. Regarding the Fuel Pump Relay. My truck only has an "EFI Relay" That controls the ECM and the Fuel Pump.

So I ran the engine for about 30 minutes in idle. The engine did not stall. I also revved the engine RPMs up to 2500 to 3000 range for a good 5 minutes.
