02 Supercrew 5.4 stalls on hot days
As the title says, I have an 02 Supercrew with the 5.4.
The engine starts when cold and runs fine but sometimes when I start it hot after running for a bit, it will stall out unless I keep my foot on the gas pedal. This seems to only happen on hot days. It was about 90 F here yesterday and I drove it to a shopping mall after supper - maybe 5 miles. It sat for maybe 20 minutes and when I re-started it, it stalled out. The tach needle just drops slowly to zero and the engine stops. It will re-start without any problem but will only keep running if I keep my foot on the gas and keep the revs up a bit. It has done this a few times in the past few years and only on hot days after it has been running and then sat for a few minutes.
Anyone encountered this issue and have an answer on what I should look at? It does not throw any codes and generally runs ok after a few minutes. For example, last night I managed to keep it going by shifting into neutral when required until I got back on the road. I drove 2 or 3 miles and at the next light, it acted like nothing happened.
