I have 1997 Jeep Cherokee Sport and it had the identical issues you were having. I changed the spark plugs with AC Delco (Recommended by the parts store). Right after I did the change, it started to hestiate in the morning. I would have to turn off the vehicle and restart it and it ran well. Nothing was wrong. After months of this, I got tired. Took it to my mechanic and he stated there was nothing wrong with it. I was looking online about this issue and there was numerous things posted from fuel lines, fuel pump/filters and even gas. But one stood out. It was regarding the spark plugs. It stated that Jeeps run on Champion spark plugs. Cherokee and Grand Cherokees. What the heck, $12 to try right. I changed them and had no problems since. It runs like it is new. Hope this helps you out.

thank you for the answer, i found the answer the ECM has a manufacture defect by short circuit from the cover, read www.cnet.com car tech forum: jeep grand cherokee stalling fixed! but loosen the cover screws about 1/8 - 1/4 in
