appears it might be in electronic module.. they can brake down when hot and cause a problem like this... I had one that did but not as quick or often, would be ru nning fine and just shut down or it would skip beats at time on start up, all kinds of weird things.. it broke down a lot at hi way speeds, just shut off like it was running out of gas, then it would pick back up it would always start up easy though..

this was in my 52 with a 235 and mallary electronic dist, no points.. may not be your deal but if it starts up easy I would not think it is a fuel issue but..

put a close pin on the fuel line........lol

good luck
