Once the engine gets hot it starts cutting out at low rpm. If I can keep the rpms about 2500 it runs fine. When the rpms drop it wants to die. If I drive it for 15 min and the rpms gets to low it dies I can start it but it takes a few minutes to get it started. If I drive it for about 30 minutes and the rpms get to low it dies and I have to let it sit for a while before it will start it. When it does idle after getting hot it surges and dies. If any body can help it'll be appreciated.

 

Check your battery condition, mine was acting similar and my alternator was shot

 

Battery connections are good. I had to change the alt. The problems started about the same time. But it acts up after it gets hot.

 

Problem fixed. It was the crankshaft sensor. On a 96 jeep cherokee country edition w/4.0 L. The crankshaft sensor is located on driver side of engine in back where bell housing mounts on engine.
