Had a very similar experience in Moab last week. No diesel shops in the are.
loss of power, missing out and starving for fuel, black smoke. Had to be towed 90 miles to Grand Junction but they replaced the fuel pump and it cured my problem. There are two fuel pumps...if the primary fuel pump fails the secondary or injector fuel pump will continue to suck fuel thru the primary fuel pump but not at a rate that is sufficient to run properly or climb a grade or hill and if allowed to do so will ruin that secondary fuel pump...$2000.00.
The primary fuel pump for my Cummins was $190.00. Good luck. Thank goodness for Coachnet.
One other problem that I had a couple years ago was a loss of power on hills and just got worse and worse in a matter of a few hundred miles.
My Cummins has a short 14" 1" or 1 1/4" hose that runs from the front of the intake manifold (underneath) to the air compressor. It had a hole you could stick your finger into at the bottom of the hose right where it connects to the air compressor. A very easy fix.
