Engine miss / hesitation

2002 7.3 198,000mi Just noticed a problem while on a 1000mi trip and is getting worse. While trying to maintain speed the engine misses, hesitates. It acts like a gas engine not getting spark. It does not do this at idle, under acceleration or with the cruise control set.
Any thoughts?

Fuel filter changed before the trip. Have not checked it since. I am going to take a look at it tomorrow and was hoping for some ideas where to start.

Mine just started doing the same thing a couple of weeks ago. It's only done it 3 times total. Usually after I start it in the morning and am headed down the road. It does it once each time and won't do it again the rest of the day. Just like a gasser loses spark on 1 revolution, just a quick sputter and thats it.

Anyway, question was, what is a CMP or what does it stand for?

Thanks

Just for the record, anyone troubleshooting their truck and stumbles across this post, new CPS fixed the hickup.

But apparently you CAN put too much di-electric grease on the connector...
It stalled out on me while driving down the road, and wouldnt start back up. I had to hit the wiring connector and the CPS with some PB blaster, after that it fired right up and been running fine ever since. Weird, I didn't think electrical grease would ever pose a problem.
