This is a lot like the old "Hold the phone closer to the car..." thing. But there's about 3 things to eliminate before you do forensic surgery. How is the condenser? Sparkling new, as in fresh...from Asia? You sense something in the coil (we know our cars like our bodies sometimes) so instinct may be kicking in. We say "vacuum advance" colloquially most times, but the reality is when vac drops (stab of the go pedal) timing retards. This is done by the point plate moving and its entirely possible it tweaks a wire outta contact momentarily. Could lose ground or primary input/output. If it's not getting proper current the coil can heat and so can the condenser. Too hot, either stops working. Rule those out before you dive into fuel. Vapor lock? I have hot summers and blended fuel (Michigan) and I haven't had vapor lock on anything since the mid 90s. There has to be a really screwed up fuel system to cause it. Random thoughts...
