Did you have the skip before the new injectors and fuel pump? If not could be one of those.

Massdiesel,

Might want to consider buying a Cummins reconditioned injection pump. I seen posts where they cost around 1200. 00 from Cummins. They are supposed to be better than the old VP44. These have the better seals.

Is your truck under warranty?

A couple days before my 98. 5 died, it developed a loping idle after the engine had warmed up. Was running great across NV and when I pulled off the freeway in the evening to get a motel room I first noticed that I had a loping idle. Drove it to San Francisco where it died a couple days later. Was running great, just wouldn't idle good after it warmed up, when loping it the rpm would vary by a couple hundred rpm.

Mass, check with Chip at Blue Chip Diesel. He is as knowledgeable on the injector pump issue as anyone. He also told me that he would sell the injector pump as cheaply as anyone. You might want to get it to his place for repairs. I would.
