losing power

my 6.9 runs good but the other day i was driving it andat a certain rpm it chugs or misses on a few cylinders, then if you stomp on it it runs good, it seems to be at a certain rpm at certain times. some times its ok. it doesnt die it just struggles. what could it be?

Hmm...sounds odd. First thing would be to replace the fuel filter, basic maintainance anyways. After that I would start looking at lift pump, return lines, and then lastly the IP.
