I have a 8 cylinder 88 gt mustang and a problem that i can't seem to find what the cause is. Every so often whenever it is hot out my car dies. After waiting a good 30-45 minutes, it'll start up. I've read on some forums about the TFI module not working when it gets hot. I relocated it to a place where it gets some air flow instead of it sitting on the hot engine. I have an MSD ignition module with MSD coil. The MSD ignition module is located underneath the dash on the passenger. I'm taking it next week to get a diagnostic done on it (again) and I'm going to have them run the car for a good hour. What could be the problem here?
