1990 Jeep YJ Stalls while driving

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.
