I would start with disconnecting the injector harness and ohm the injectors. Because of the way this is wired 1 shorted or open injector can cause your concern.
Did you replace #6 injector? If yes did you enter the injector flow rate into ECM with a scanner?
The ECM will derate the engine and put it in "reduced performance/limp in mode" if it detects low oil pressure, but won't shut it down completely.
As per your symptom description and the codes you posted, the problem seems to be the ECM is not detecting the injectors - most common cause is open pass-through connectors. However, if the injectors can be activated with the scan tool, then the issue is most probably caused by a bad ECM.
Were you able to activate the injectors with the scan tool?
