Can somebody please help my car will start for less than a minute then cut off with the message on the dash saying “engine power reduced” once the message pops up the car won’t even crank up anymore but all the light and everything work when the car is in the on position… if I delete the code with my scanning tool the car will start up again and then shut off while idling and the message will pop up again… I tried replacing the battery so I know that’s not problem
