Engine loses power after 2 hours of driving
I have an '86 4wd with a 318, automatic transmission and disconnected smog pump. She has 101,000 miles.
After 2 hours of highway driving, the engine misses and stumbles to the point I have to stop.
After I stop, shut off the engine, and wait 5 minutes, I can restart and drive for another 2 hours before this occurs again.
After I experienced this problem the first time, I installed a new fuel pump, filter and flushed the fuel system.
I do not know what to do! Is this an emissions issue, a vacuum issue or a sign that she just doesn't like long trips anymore?
Please help!

Temperature and fuel pressure are good. I have recently replaced the coil, rotor cap, button, fuel cap and tank vent line.
She's still misbehaving.

New to site. I am having same problem with my 1997 Ram, 5.9. Put meter on computer an got a reading that says that cylinders #1,3,5,7, are misfiring. This problem came up after driving about 15 min. Like you I changed rotor,cap, and pickup as was told by Dodge Mechanic.
