1993 jeep grand cherokee?

[hawkboy1]

my jeep started having problems a few days ago, it would stall while driving but it would start back up. then it would start and die. now it wont even start. last august i put in a new/rebuilt computer and it ran fine but it only had a 1 year warranty. is it possible the brain has gone out again or im i barking up the wrong tree
