Thanks for your response,
I missed to tell that I have another p28 here with an ostrich.
This is actually not causing the main relay / fuel pump to trigger.
So I can orettyuch nail it down to not have a wiring issue in the car.

Was driving with my b18 turbo over last days.
Car is running on P28 with S300 without issues.
Out of sudden engine died and did not restart anymore.
Ecu fuse tripped and was replaced.
Ecu remained dead and was exchanged with a good P28.
Ecu is now up and running again, S300 is working ...
