5.8 power loss? Help!

Hey guys, I have a 1996 f-250 with the 5.8. I notice that it looses power sometimes between 1500 and 2000 rpms. The truck runs great and seems to have no problems but this. It isnt really like it studders or jerks it just seems like it suddenly doesnt have all the power it should and then it comes back. Anyone have any ideas? What could this be? Thanks alot, Mike

Have you tried pulling codes yet. It could be something the computer is seeing but not enough to trigger a CEL.
