Ok, so you've replaced the ECU, the coil, the ballast, and are now checking the distributor.


any chance that this is NOT ignition related? maybe it's fuel related? is your tank vents plugged up putting a vacuum on the fuel system, which then causes air to suck in from the carb to relieve the vacuum in the tank. or maybe your carb is heating up too much and you're getting vapor lock?

next time it happens, quickly check for spark. if you have spark, then maybe your problem is not in the ignition system.
