Chevrolet Repair: Fuel system, chevy s10 blazer, s10 blazer

Question
Re:  96 Chevy S10 Blazer
Blazer running good then 2 wks ago would not start. During trouble shooting noticed I could not hear the fuel pump start as before.  Mechanics determined that was problem & replaced it.  The next day it started cutting off when I stopped at intersections.  Master computer does not pickup any code, mechanics (3) cannot determine problem and gave it back to me.  Towed back to shop twice for nothing.  I filled it up w/Super Unleaded (used regular unleaded) and it stopped doing it, so far.   Could this be a air or fuel censor problem?

Answer
Hello Tracy,
I have had the wires inside the fuel tank be loose on the rivets that connect them to the cunnector outside the tank. Would work sometimes, and not sometimes.
Just a possibility. I would check for voltage to the connector before dropping the tank.
