I had this problem and found and answer on the internet. Find your computer, mine is next to windshield wiper water bottle. Pull off the plastic cover than unplug the leads to computer. You will see two screws back them out one turn. That is it. Some how the cover is shorting the computer because the screws are to tight, Mine is a 1996 Cherokee Limited.
I HAD THE same problem.... 87,000 2000 grand Cherokee 4.7l
when i let off the gas it might stall. happens 1 to 4 times a day.
so far i have
replaced the crank shaft sensor - it stopped stalling for 3 days $130
cleaned the throttle boddy free
replaced the throttle position sensor $72
replaced the idle air control sensor $132
replaced the map manafold airflow sensor $125
no luck it is still stalling. by the way i have done all the work myself. it was about 30 minutes for most parts
i just ordered a rebuilt ecu or pcu engine control unit. they program in the vin, mileage and part nbr so you gc will recognize it. $185
installed ECU 2 days ago...... so far so good.
good luck
Chances are it is the alternator. I had a very similar problem, but I had a short in the stereo wiring. Try to start it with the radio, a/c, lights, everything off
why does my 1997 Jeep Grand Cherokee start fine sometimes other times hard start and and cuts off?
The most common cause for your 1996 Jeep Grand Cherokee to randomly shut off is a bad fuel pump. The fuel pump will get worse and eventually the vehicle will not start at all.

My 01 Grand Cherokee had this problem. Sometimes you turn the key and it starts up just fine. Other times you have to turn the key several attempts before anything happens. Sometimes I have to get it jump-started. The extra power from a second battery will overpower the dead spot and it will start right up.

Does it turn over? Does it have fuel, spark and compression?
make sure your wires are correct from the distributor or you will never start
My 1995 sometimes doesn't start for several days in a row. Consider yourself lucky!
yes it will, start swapping!
1996
Check the battery.
crank or cam shaft position sensor is sometime the issue.it will not fuel if it cannot find the position of the cam or crank

If the anti-theft will not let a 1999 Jeep Grand Cherokee 4. 0 start, it will need disabled. The owners manual will instruct you on how to disable it.

check the crankshaft sensor
This is often from a dead battery.
Commonly CKP sensor or Starter. What does it do when you try to start it? clicks
