yj idles fine, then sputters, then dies

any help greatly appreciated

im a do it your selfer and love working on cars, but im not a mechanic, so i cant really diagnose.

ok so my yj started sputtering while driving a weeka go, it would quit for a few days, then do it again. changed out the plugs and rotor. tonight it sputtered bad, then just died
i got it home and it idles well, then starts to sputter after a few minutes, then sputters hard and dies
i can start it back up right away and it repeats
any ideas
injectors? o2 sensor, tpc?

If it idles fine and only dies when you accelerate that sounds like fuel filter issue.
