Update
I had a very good and experienced PSD mechanic come over last night and hook up his $3,000 scanner (snap-on) to my truck. Everything checked out good, no injector codes, buzz test passed on all 8, and even oil pressure is awesome on cranking. He tried a few other tests like trying to keep it running, checking for fuel flow to the bowl, etc. Everything else was showing good, and he says it is definitely a fuel supply problem.
So, today I get to start at the front and work my way to the rear to one of the tanks. Hopefully I will find a plugged line or something to that effect so I can at least say "I found the problem and fixed it"!
Thanks for the help guys! I will post updates when I find the problem.
