Pressed send to soon no faults found
Expert:  Mike Kelly replied 3 years ago.
With all of the test that has been done, the way this happens and the symptoms, is all consistent with a fault with the ECU and the communication with the vehicle. I understand that the ECU has been checked however some internal faults do not show under normal testing.

The ecu was sent to an official test centre
Expert:  Mike Kelly replied 3 years ago.
If the ECU was eliminated then the main engine harness has to be checked next for a short or back feed.
