when it does it, you need to unhook the fuel line after the fuel pump, and crank it, to see if any gas comes out. if not, bad pump, or vapor lock, or screen in tank id full of something. once it sits for a while, everything relaxes, and it allows gas through. when you put gas in the carb to fire it, it creats a vacume off the seat and it opens. my bet is on rebuilding the carb, I think it is blocking off the carb, the fuel pump is trying to pump, and heating up trying to do so, which causes a temporary vapor lock. I only say all this, because I went through it with my mustang, and it took me 2 years to figgure it out
