86 F-150 just dies.
I have a rock stock 86 F-150 with the 5.0 EFI V8; runs fine, except for in hot weather it will sometimes just die. No check engine light, not overheating, fluids all are ok.
Let it sit for a few minutes and it will start back up. Happens in hot weather a lot more than cold. Symptoms are like a vapor lock except this is an EFI Motor. Someone mentioned the ECM module as a possible problem.
Any one have any suggestions?
Thanks in advance.
