Ok so my '94 Z28 with 30k on my new engine has this issue, only happens when I drive around a lot, freeway or in town, and when it is hot outside. I'm talking temps around 100 and humid. Monday I drove it about 100 miles, hot outside, came off the freeway and headed home obviously at slower speeds. I could hear the fuel pump kick in and shortly thereafter the car died. If I tried to start it the fuel pump would kick in and it would not start, like it's sucking air. You could smell the gas fumes in the car and I took the gas cap off and got a loud suction noise. I waited about 10 minutes and it started right up. This is the second time in a week it has done this, pretty much the same scenario. It is my daily driver and takes me to work about 40 miles per day. I have no problems with this otherwise.

Suggestions?

 

could be the wiring getting too hot or the pump itself. is it the original pump? or was it upgraded or swapped out with the new motor?

Thanks for the info, and yes I believe it is the original fuel pump. I've had the car 2 years and have not replaced it in that time period. Just the engine, water pump, radiator, hoses and such to get the 3 year unlimited mileage warranty.
