Dodge experts:
I have a 1995 Dodge Ram 1500 pickup with the 5.9L V8. The truck has about 70K miles on it, and I have recently been having some power loss issues. The problem I have is if the truck runs at highway speeds for about an hour (my commute is 1.5 hours one way), the engine will suddenly lose power, backfire, and will stall. I can re-start the engine, but it will run very rough. Even when it runs a little smoother, the engine has no power (I put it in Drive, but the truck barely moves). If I let the engine cool down for about 15 minutes, the truck will run fine.
I just replaced the spark plugs, spark plug wires, rotor, distributor cap, and air cleaner with no luck. When the engine dies, there is no "check engine light" that comes on. I have yet to replace the fuel filter.
I have done some investigating, and it looks like replacing the MAP sensor and/or the crankshaft position sensor may help. Before I invest any more money, however, I thought I would ask for some help.
Any ideas on what is causing my problems???
Thanks for the help.
