[Mr Chevorlet]

That is the same issue i was having, i could drive for a while and after about 20 minutes it would cut out and after it set it would run and idle fine and did this over and over. Still could not find the issue. So one day in the shop i noticed i had a intake oil leak in the back that was bothering me so i decided to pull the intake, put in new gaskets and front and back seal and reassembled everything, oil leak stopped and low and behold i drove it around and have been for a couple of months and the no cutting out or missing no nothing. I know this is not going to help you because i do not know what it was for the life of me. I think it was either the carb gasket or something with the distributer.
