Tom-
I had a similar problem...Not being the mechanic type, I just figured it
was overly-sensitive to the quality of gas I put in...
It usually did it right after I fueled up at a BP with the lowest octane
gas...if I put 90 or 93 in, it would occasionally pop, backfire, chug,
and loose power, but not as bad as the lower octane stuff. Heet would
actually temporarily take care of the problem.
I also thought it might have been a fuel pump or filter issue.
FYI- This was a 2002 Dakota SXT with the 3.9.
