stalls out after 15 minutes

 

Ok

 

It really helps to provide as much detail as possible and ask specific questions.

For example, your 96 XJ stalls out after 15 minutes. Can you get it started again - if so, is it immediate, or do you have to wait for the engine to cool down and then it will restart?

What have you done so far - both in terms of recent work done on the Jeep and for troubleshooting?

Have you checked and cleaned all your grounds and battery cables - not looking at them - actually taking them apart, cleaning the contact surfaces to shiny metal and reconnecting tightly. If not, you should do so before anything else - it's quick, easy and cheap and the experts on this forum will always tell you to do it before anything else.

 

Then you should be specific - are you asking for common faults or troubleshooting steps?

If I can assume that you are looking for where to start and what could be wrong - I will say that no matter what - start with the grounds and battery cables as mentioned.

Next you can consider two possible thoughts:
1 - Stalling after the engine is warm and being able to start after it cools off is a common symptom of a bad CPS - they can be difficult to test and aught to be replaced with a Mopar part. If you have a manual, it's far less likely to be the CPS.

2 - Fuel pressure - this is the first test that I would do. You can usually rent a test gauge for free from your local parts retailer.

Oh, well in that case there's nothing we can do to help.
