Here The Fix
 

I GOT IT! It's been a test of patience and reminder to pay attention to details and don't get roped into following what is common.

The problem that has been plaguing my 2003 6.0L was a piece of wire or spring that was stuck in the RH HPO Rail Check valve. I presume that with the check valve stuck open the high pressure oil was fluctuating locally and not being recorded by the icp.
