Along with the vacuume leaks I would check the carb. The accelerator pump might be out of adjustment or something else in the carb. Currently I have the same problem with mine and I just adjusted it and for 1 day so far it's ran fine but I have a holley on mine. Carb may be dirty also.

Could be vapor lock in the fuel system. Next time it does this, stop and try removing the fuel filler cap... Hope this helps...;-)
