Gentlemen,
Thanks for the input so far. Currently sourcing the needed parts and tools. The problem that concerns me is the intermittent nature of the problem. How could the truck run without issue for 10 miles between events with the 10 miles having similar loads on the the engine. I suppose the fuel pump tests may reveal some weaknesses, and once I take the fuel filter assembly apart, if I am lucky there will be a smoking gun.
I guess a borescope is the next tool required so I can look for arrant rubber and or grasshoppers in the fuel tank!
