I have a 1994 Ford F-150 with a 302 cu.i. engine, automatic transmission and dual gas tanks. This problem happens every 4 or 5 months and never more than once at that time.
I will be driving my truck and then stop somewhere for a short amount of time and when I go back to my truck and start the engine it will die immediately. It will continue to run as long as I keep my foot on the gas pedal but the moment I remove my foot from the gas pedal the engine will again die immediately. I normally will wait about fifteen or twenty minutes and then try again and the engine will start right up with no problem and will behave normally.
I have tried to explain this situation to my mechanic and he has no idea what I am talking about. I have had him check everything out and he can find no problem. It has been suggested to me by friends that the problem could either be with the alternator, battery, or vapor lock....
If anyone has ever had or heard of this problem I would appreciate your help. This problem happens so infrequently it is hard for me to diagnose.
Thanks,
