Runs for fifteen minutes and shuts off

Hi and thanks for using 2CarPros. Com. The two codes you listed that have my attention are the 1299 and the 320. Either of these can shut the engine down. The other two codes will not shut off the engine. The 1299 is specific to engines that have a plastic intake manifold, so you will have to check which yours has, steel or plastic. I have attached a flow chart for you to follow if you find it is plastic. It will be the first flow chart I have attached.

Next is the 320. This code is related to the crank sensor. I have attached several flow charts to diagnose that issue. My gut feeling is the crank sensor, but check both things.

Let me know what you find or if you have other questions.

Take care,
Joe
