My 95 Laredo did this when I first got it. It only stalled when backing out of my driveway, cold and hot. I got bored one day and decided to change my fuel filter. When I pulled the old filter off and dumped the contents out, it looked like black muddy gas. When I started her up later that afternoon, she purred like a kitten. And when I reversed out of the driveway, there was absolutely no stalling. None.
A couple days later I cleaned the TB real well and gave the Jeep a Seafoam treatment. She ran even better. I had that Jeep for another year after that and never any other stalling problems.
Hope this helps.
