Need Help Engine cutting out

I have a 94 4cyl. It has been cutting out while driving. Not in nutreal. It only does this once it is warm and not everytime. I have replaced plugs, wires, fuel filter, etc. I somewhat new to the jeep and was hoping someone could help.
Thanks

sounds like a classic CPS problem to me. crankshaft position sensor. they're a common problem. does it start right back up or do you need to let it cool off a bit first? also, try running the codes and seeing what that turns up. the procedure is in the FAQ

Since it only does it under load it does not quit. If I stop there is no problem.

I had the same problem with my 4.0L, I replaced the fuel pressure regulator on the fuel rail and that fixed the problem. $52.0 at AZ

Have you checked the self-diagnostic computer codes?

I'm going to check fuel pressure tonight. There are no error codes coming from the Jeep.

well if this is the case then i doubt it's the CPS. when you said cutting out i figured it died instantly. this sounds more like a bogging/stuttering problem and without a code to go by then i would suspect fuel delievery as well. definitely check the fuel pressure next
