Can anyone tell me anything left that could be wrong

Most likely a wiring issue. What does fuel pressure do? If it is dropping before the car acts up, the wiring or relay for the fuel pump is bad.

if it were a wiring issue I wouldn't be able to feather the peddle and keep it running it does have a new fuel pump relay also ,do you think maybe the fuel regulator,or might as well replace it cause it's the only thing I haven't?

IF YOUR VETTE HAS FUEL INJECTION FUEL PRESSURE REGULATOR COULD BE THE PROBLEM. YOU GIVE IT THROTTLE AND IT DOESN'T DIE, MY GUESS IS THE FUEL REGULATOR IS NOT CALLING FOR ENOUGH PSI. YOUR GETTING THE OPPOSITE OF FLOODING. AND YES I COULD BE WRONG. GOOD LUCK

I have had te same problem and I bypassed the vats systemI* also I noticed that the voltage dropped below 11 volts and that caused the fuel pump to shut down
