It will start back up after it cuts off

Hi there. Replacing the ignition control module, you may have touched on something that allowed your engine to run fine for a day. The fact, it runs fine for a couple of hours and then starts sputtering and dies, leads me to believe a component is breaking down. This could be any number of possibilities, a faulty ignition coil, high resistance in the spark plug wires especially the coil (stinger) wire. The distributor cap is a fairly common failure. This could also be a fuel delivery related issue. Replacing components without diagnoses, can be expensive and time consuming without resolution. I recommend having your vehicle’s sputters and dies be diagnosed and repaired by a certified technician, such as one from YourMechanic.
