I have a 1984 ford f 150 with a 4.9L 300 6 cylinder engine. It starts and runs good when started cold. After it gets to operating temperature it will die out and is hard to start. It will start after sitting a while and die out again. The distributor has been changed and the ignition module, plugs, plug wires, carburetor overhauled, radiator and thermostat, and the timing has been set. It still dies out in about ten to fifteen minutes of running. Catalytic converter has been by passed, cut out. A I R system is not connected either. Need help fast.
