95PSD runs rough after 15-20 Min.

After 15-20 min it revs up by itsel and runs rough. What do I need to check?
The injectors were rebuilt and have less that 2000 miles on them. New fuel filter.

Curious if you figured this out. I have the same problem- starts fine and idles at 700, then randomly will rev higher for a second, check engine light comes on and then it idles rough(still around 700, but loping).

UVCH inside and out. Anything burnt? Solid connections?

IPR tin nut tight? Orings good? Harness chaffed?

ICP sensor going south (unplug it and see if it steadys).

Exhaust back pressure tube clogged?

FPR screen clean?

There are some of the things off the top fo my head that i would check.
