Jeep starving for fuel sometimes

My play toy is a 1993 Jeep Cherokee with the 4.0 auto 4x4, nothing special at all. Recently I got in it and it started right up put in reverse and it died, started right back up took off fine, then died again later. It then wouldnt start again the fuel pump sounds like its running fine. I thought it was a clogged filter so I replaced it, then it started right up ran for about 5 min and died. It runs fine when its running other than a studder when you first get on it. Could the fuel pump be weak? A regulator problem? Anyone had this happen before? By the way it is MPFI and sometime it wont even start for awhile just crank and crank. I know its in the fuel just not sure where at. Thanks for any help!

I would recommend checking the fuel filter again and see if it is resricted. You may have a bad tank of gas.

I had a 99 Cherokee with the 4.0 L that cranked forever before start. I was told that it was one of the idiosynchrosies of the motor. I finally found some info on Alldata that helped a lot. One of the hoses in the tank attached to the pump loosens. I pulled the pump and put a new hose and better clamp on it. It helped a lot, although it still had a longer crank time than I liked. It wasn't too difficult.
