The truck sounds like the timing is really retarded (clattering like a diesel) and the throttle response MIGHT be about 10%. Turning the truck off for a couple mi utes then turning it back on will allow proper operation for a few minutes then it reverts to limp mode.
Thoughts? It's gonna be a long ride home over Teton Pass...
