Other Fuel System Pump problems of the 1996 Chevrolet 1500

I have a 1996 Chevrolet c1500 originally equipped with a 5 liter which was replaced with a 5. 7 liter. I replaced the fuel pump and sending unit due to the old part was no longer good. Within 2 months the new part shorted out, frying one of the wires on the inside part of sending unit, inside the fuel tank. I again replaced the part thinking I had bought a defective item the first time. I am now starting to get the same symptoms it had the last time right before the last sending unit went out. I did an electric check on the old/new fuel pump and it was o. K. . The symptoms are, when I'm coming to a red light the vehicle stalls out and dies. I put it in neutral, crank it, and it starts back on. It did the same thing last time until finally it failed to start. I know of a 1996 Chevrolet astro with a 4. 3 liter and it also suffers from the same problem and uses the exact same part number. Any suggestions that do not involve tnt would be highly appreciated.
