My '03 Durango w/ a 4.7 is having issues intermittent but frequent with missing. Usually not real bad, but once in awhile, as it did yesterday afternoon, it will pretty much fall on its face, RPM's go way down to where it almost dies but doesn't, and it will pick itself back up and idle and run just fine. I was advised to change the fuel filter, but I know that is not the issue, because I just replaced the fuel pump assembly a month or two ago, and the fuel filter is built into the fuel pump to my understanding (right?)

Does anyone have any ideas or things they could suggest I check out or replace to try to resolve this? Any help would be appreciated. Thanks!

Might still be the fuel pump, as the intermittent operation sounds like the pump has an internal fault or there is ground problem with that part of the wiring harness.
