Default spitting and sputtering

this morning i went on a cruise with some buddies, after a few miles my car would spit and sputter while cruising in 5th gear. downshifted to 4th to raise the rpms to around 3k, it quit and began to run good again. after a mile or two of that it began to do it again. so id get in it, sometimes even dropping a gear/punching it and it would quit then once it got back to cruising rpms 2.8k or so it started again. i basically dealt with it for the rest of the morning. once i left to go home it got real bad. even when i would get in it hard it would spit and sputter real bad. almost barely running. but theres no knocking or banging coming from the engine bay. the exhaust note changed quite a bit which makes me believe that its running rich. the exhaust note went from crisp and clean to almost muffled and quiet. all the plug wires are hooked up and it has brand new plugs that are two weeks old. the car has never done this or even ran bad for that matter. does it sound like a fuel issue or somethin else?

mods are:

232/234 on 112 lsa
QTP Lt
TDs dynomax bullets
slp intake
u/d pulley


any ideas guys?
