2.7 CRD suddenly dies while driving. DTC for random injectors p020x

[Faniskogen]

First post here but long time lurker from Sweden!I bought a WJ 2003 2.7 CRD this winter and Im so happy with it! It has a bit over 290k km on it.

Now it has started to die on me while driving. It runs great and then suddenly just stalls and the CEL lights up. I stop and then it just starts as normal and drives as normal but with the CEL lit. If I turn it off and let it sit for a while the CEL is gone at next start up.
A few times, it have been hard to start it up again after a stall. Starts but idles rough for a second and dies again. After a few tries or maybe a minute wait it will start up and run fine again.
This can happen after 5 minutes of driving or not for a whole day.

I recently replaced a bad injector nr3 and seals for nr 1. But it have been driving fine for a while after that until this started happening.

I get DTCs for the injectors, usually a different one each time. p0201,p0202,p0203,p0204,p0205. I have erased the DTCs and they come back one or several at a time after a stall.
The p1601 is a new one, came on today.

I checked the harness that goes by the steering rack and it had been torn a bit but I could not see any damages cables. I wrapped it up with some rubber hose around that section but the problem is unchanged.

Please, do anyone have a clue of what can be the cause of this?

I have this problem intermittently too on the number 3 injector for some reason.

I usually fix the problem for a while by reseating the injector connector. I'm going to do a lit bit more cleaning and lubrication with some WD-40 I think. Certainly can't hurt.

Thank you for your replies!
Do you always get a dtc for number 3? I l will try to reseat all the injector connectors with some electrical cleaner spray.

Sounds like a costly problem! Where the symptoms similar?

For me always number 3.

It got worse until it went all dead had to replace the ecu

That would feel more easy pin pointing the issue. For me it's always a random injector that gives a dtc. So I don't think that a single injector or connector is the issue for me.

OK! It do feels like it's getting worse. I think I will let a mechanic take a look at it.
I hate these kind of problems where it may or may not show the symptoms for a whole day or in 5 minutes of driving.
