So I recently came into ownership of a 1999 300m that will start normally when cold, but around 20 minutes of operation, the car will shut of and not start. It will crank, but not give any indication that it will fire off. It does not misfire or sputter before it shuts off, nor does the check engine light come on. When using a scan tool and going into the enhaced dtc, i get a p0320 code. The crankshaft and camshaft sensors were replaced at one point, as well as the pcm most recently. the problem has both my father and I stumped.
followed wiring to the crank sensor?
