I have 94 Dodge Ram with the 5.2L engine. After about 15 minutes of driving it will stop firing. Once it sits for about an hour it will run for another 10 or 15 minutes. I have replace the ignition coil and the pick up in the distributor. I haven't been able to find an ignition module on the truck so i am thinking it is built inot the ECM. Is this correct??? I don't want to change anymore parts without knowing it is going to fix the problem...the truck is too old to waste a bunch of money on and not fix it. Do you have any other ideas as what it could be? Thanks
