Question about 1996 Jeep Grand Cherokee
After this changes, you reset the ECU? Sometimes this is need to
Are you make scan to read fault codes?
When it dies (if do it) does the Engine Light come-on and stay-on? If so there are codes which are present that can isolate/point you to a more specific problem.
I would first check your spark plugs, wires, and coil. When were they last replaced? If these are fine: when was the fuel filter replaced? air filter?
Check the fuel pressure at the port located on the fuel rail in the engine compartment. If those check out OK; I would check and/or replace the Idle Sensor and/or the Throttle Position Sensor.
Basic rules on bad idling:
* Fuel, is there enough getting to the cylinders?
* Spark, is there consistent spark getting to all the cyclinders?
* Air, is there a air shortage = clogged air filter?

Engine stalling and rough run
issue at low speeds
is commonly caused by a dirty automatic idle speed control valve and
throttle valve. Buy a can of throttle valve cleaner (do not use
carburetor spray cleaner!) from NAPA or Carquest (made by CRC
chemicals) and spray it into the air intake while the engine is
running, use up about 1/2 the can, engine will try to stall hold the
speed up, shut it down and let it soak for 30 minutes, restart and
blow out the remaining fluid, shut it down and disconnect the
negative battery cable for 5 Min's to reset the base idle control
