Finally a solution:

The problem ended up being the HEUI pump.

The pump nut backed off the beveled sprocket and was free spinning. We cleaned, lock tite and torqued to 75 LBS.


Truck fired up and we are a few hundred miles down the road cruising at an average speed of 68.

Finally a manufacturing defect attributable to Cat not S&S.
