Hi. I thought I would see if maybe a forumer could help me diagnose a problem I'm having with my 1991 Ford Mustang LX 2.3L. When I drove it across the country 2 years ago everything was fine until suddenly the engine shut off. All the gauges indicated I was not over heating. I waited a minute or two and then the car would start. It would run for a minute or two and then shut off again.
If I waited about 15-20 minutes and restarted, I could drive for another 45-60 minutes on the Interstate before the engine shut off. I had two mechanics look at it, and they were unable to find anything wrong with the car.
I attributed it to high altitude, heat, and long distance driving. I did not have any problems until I drove it long distance again, when it shut off on me. I waited for 20 minutes, started it up, and it ran fine.
Yesterday it was hotter than usual, and I was making short distance trips. My car just shut off again. It was not overheating according to the gauges. I have recently replaced the radiator and the internal temperature control part that kicks on the fan when it gets too hot.
Any ideas what is wrong? Could it be vapor lock? If this is the case, what do I need to have done to the car, and how much might that cost? Thank you.
