I have a 92 tempo 2.3L fuel injected engine that runs great until you try to take a 30-40 mile trip in hot weather 95-100 degrees. At highway speed, the car will suddenly lose power and die aprox. 20-40 minutes into the trip . car will restart immediately and runs for a minute or two then starts cutting out and dies. Temp gauge says it's running in the normal range, radiator fan is running. If I let it set a couple of hours it runs fine again. Car will idle smoothly for hours in my shop, and runs fine in cooler weather. Had the TFI checked today, they say it's okay. put on a new fuel filter and spark plugs. coil failing when hot? other ignition component? vapor lock? flakey fuel pump? TFI that only fails when extremely hot? any other ideas are welcome. Thanks in advance.
