When it does this and won't restart, have you checked to see if the plugs are getting spark and fuel is getting to the carb?

I have to be honest, it has been awhile since I worked on one of these. However, I remember this type of problem really well. Every time this would happen, the ignition control module (the aprox 4"x4") box under the hood was the problem. They would go bad, heat up, and the engine would shut off.

Let me know if you lose spark. If you do, the ignition control module is my first guess.
