Could be a fuel related issue too. If it is leaning out it will do what you describe.

Mopar electronic distributor or something of that design?

It could also be the distributor itself. The electronic pick up unit inside the distributor could be failing with the heat. I had a unit once that caused the car to die as it got hot, swapped the distributor and all was OK.
