Have you got an electric pump you could just wire in temporarily?
I'd use a fuel can in the box and jury rig a fuel line with an electric pump. That would tell you if it is the fuel supply side or a failing VE ...

Well, First I'd make sure that the big plug with the three sided head that covers the end of the pump piston in the distribution head is not loose.
It probably isn't, but I saw a truck once with a constant start/power problem due to that being loose.
I would check the return line for a clog, just for grins.
The only thing after that I can think of is a crudded up advance mechanism that is sticking in a retarded position. You could take the KSB off the pump & open up the fuel inlet, blow out the fuel return passage from the end of the advance piston back to the inlet & see if anything comes out, or if it is plugged up. It could be done in the truck w/o a pump R&R.
Please let us know if you figure it out.

As far as the return line clogged I cannot see that being the case, as when I ran the truck off 5 gallons of diesel from the bed, I only went about 10 miles max and it nearly drained all 5 gallons, so I figured it must be returning it to the tank the unused fuel hence the return working.
