Unhappy Wrangler intermitten issue please help

Hello i have a 1994 wrangler, i have recently had problems with it, it has the 4.0 fuel injected inline 6 motor. intermetenly it has been dying out on me, i have replaced the fuel pump. and fuel filter. I have no idea what to do, i have tried checking for relays/fuses and nothing has worked. could it be a sensor? if so which one? Let me know what ya guys think!

Ingredients for proper running:

Well timed spark sufficient to ignite.

Mechanically sound engine with all parts properly timed.

Good fuel and fuel/air mixture.

Assuming that the engine is mechanically sound and there is adequate and properly timed spark, that leaves fuel and fuel air mixture.

A vacuum leak can cause rough idle and poor pickup. I would start there.

You can spray starting fluid or carb cleaner around areas you suspect a vacuum leak. If the engine picks up, you have discovered a leak.

An engine analyzer can detect problems with spark and timing.

That would cover most of it.

We have a vocational school here in town. They would put my jeep on their analyzer and be able to tell if it is getting adequate spark and at the appropriate time. Something to check out in your community if you have one. Or just put it into the shop to have it checked.

Sounds like heat is your enemy, check the ignition module and coil

My 92 was stalling. I checked the coil by grounding the wire looking for spark. It was intermittent...new coil and I am running....good luck
