Got a 1987 GMC 1500 with a 350 throttle body and 260,000 miles. Truck runs great cold - but when hot - engine dies when accelerating from a stop sign or light. There are no error codes in the computer. Have changed plugs, wires, cap, rotor, reset timing, etc. Have took this truck to several mechanics - heard everything from "distributor 'may' be magnetized" to " you 'probably' have a bad ignition switch". Please help on what to look at next.... Thanks

New Plugs, wires, distributor cap, rotor, set timing, checked idle speed, and replaced the fuel filter. I guess next to check the coil and the fuel pump pressure?
