New video by Dana Nance
does the video look familiar? Especially starting around minute 4.
that was just ideling in park after a drive. That's on standard alcohol pump gas.
on hot days if the under hood temps got up there from sitting in a drive through lane, I would have to take it super easy once i hit the road again.
the main symptom would be pulling away from the first stop light under normal acceleration, the engine would start to die, if I lifted the pedal it would recover and if I took it easy for the next 30 seconds or so it would be fine after that.
after I switched to alcohol free gas never had the problem again.
there are things that can be done like a fuel vapor return line and a 3 nipple fuel filter designed for the purpose.
put a higher pressure fuel pump in and regulate right at the carb.
good luck
