Problems regarding fuel system on 1998 Dodge Ram 1500

NEED MORE ANSWERS/ THE ANSWER THAT I GOT TO MY QUESTION WAS ALREADY ADDRESSED AND IT IS NOT THE PROBLEM; BUT, THANX ANYWAYS, NICE TRY. Truck runs fine at idle - when you put it under load it will not exceed over 20mph then truck runs rough. NO ENGINE LIGHTS HAVE APPEARED OR FLICKERED AND NO MISFIRES, OR CODES. What could be causing this problem? What kind of repair parts are needed to correct this problem? What would the cost for replacement parts be without labor? Where would I be able to purchase these parts?

If I were a guessing man, I'd say you have a check eng lite on. Maybe it even flashed one time or two going down the road. Sounds like a plugged catalytc convertor, do to a misfire that youv'e ignored.

drop fuel tank and check that fuel filter is in place and the intake pipe for it is not rusted off.
