It would be under fueling correct? And it would be constant not intermittent

Correct on the under fueling. From what I have read it starts throwing a code on hard pulls and gradually gets worse, that being said the truck will run for quite awhile during failure. I purchased a truck that had the cm2250 that was not running and the issue was the ceramic plungers in pump ....furthermore from the internal damage I could tell it had run for awhile during failure.
