Loosing fuel pressure
My 98 Cherokee is loosing fuel pressure. When it is at full operating temp if will either shut itself off or kick back up and idle fine. If it kicks back up it will keep doing the little process of starting to shut off , kicks back up, idle levels out and starts over and eventually it will just shut off. I put a fuel pressure Gage on it will it was doing this and it drops from 50 to 20 psi. What could it be? I got another fuel pump to put in it today.

Replace that pump assembly and that will likely resolve it.
Don't use an Airtex. No lack of problems with that brand of pump.
My favorite brand of fuel pump is Bosch. Best in the business and worth the extra cost.
