Try scanning for codes while the Jeep stalls. Are you sure some of the sensors are still the originals? Cam, Crank, Fuel Pressure?

Fuel leak from fuel lines (plastic and/or high pressure)?

It still only throws the low fuel pressure code. There are no bubbles visible in the fuel lines and no leaking fuel at visible.
I have no idea if the crank, cam, fuel pressure sensors are originals.

A faulty fuel pressure at the front of the fuel rail(towards the radiator) often causes that code and stalling during heavy acceleration.

I could always try a new fuel pressure sensor because it's cheaper than a new high pressure fuel pump lol.

The code was 1130. I forgot to put it in my last post.

It's more likely an issue with the fuel pressure regulator at the back of the fuel rail. What is probably happening is the ECU commands a certain fuel rail pressure. If the pressure regulator can't deliver the goods the ECU will complain and often stop running, or I've seen the CEL come on on mine in this situation and the engine hesitated then returned to normal when the load was removed.

Given the KM's this is what I'd be inclined to replace first. It's a pretty easy job to do, but you do need to remove the fuel rail to change the part out.

Just and FYI, our version of the OM612 doesn't have this sensor on it so it won't be the problem.
