1995 Chevy Truck fuel injectors not sending fuel to TBI

I have a 1995 Chevy C1500 truck with a 5.7L engine and TBI, it has 125,000 miles. I replaced the fuel pump which works properly now and no fault codes appear on diagnostics. MY truck will start when it is cold and runs for appx. 10-15 minutes then fuel stops spraying from the injectors and the vehicle dies. When I try to restart I smell an electrical burning smell from the passenger side engine compartment and engine will not start again for a couple hours. I've heard ECM, fuel pump relay and ignition switch. Any ideas please!!!
