Intermitently, meaning some days it will go miles with out a problem, other days it is so bad I want to put a match to it.
As it is driving up or down the road or even a level road, it feels like the engine is cutting out. If I slightly press the gas pedal the engine comes back to life as though someone flipped a switch.
When approaching a stop the engine will begin to sputter and idle very rough to the point it seems it will die. Occasionally it will die while idling, not while driving.
To date I have replaced the in tank fuel pump (what a pain in the rear that is), the fuel filter, and today the throttle position sensor.

check all your vacumm lines along with throttle body tightness....could run some injector cleaner in it also could check spark plugs and wires it never hurts to replace them

The vacuum lines could be an issue, they seemed messed up when I got the Jeep. Any idea where I can get a schematic of the vacuum lines?
