Thanks for the advice...sorry this turned into an accidental tech forum-type post.
It did feel like vapor lock. The engine was running hot (210-220). It has a new carb, and the mechanic removed the two inch spacer which he said was probably for heat isolation. I told him I was OK with removing it because it meant I could finally see with my rear view mirror. Maybe it needs to go back in. The fuel pump has been checked.
