Car shutting off while driving.
This is an issue that had first started out very rarely and intermittently at first was thoguht to be the battery or alternator because the car would occasionally have starting issues and these long cranks about the same time as putting in a big amp that I thoguht may have been sucking the battery. I have since removed the amp and all components and the problem has progressed to the point where the car will simply stop running while I am driving. I've let it sit on those occasions (in the middle of a mcdonalds drive through on one occasion) and eventually the car will start up again. I've been reading up on this and thought it must be the crankshaft position sensor and ordered the part got ready to install it but noticed that one of the air intakes to the engine was not fully attached.. Could this be the problem? It has a big enough gap to let a great deal of air escape and i've read that in some cars that they can shut the engine off if this is the case. Could this be the source of my problem or should I still put in this new cps? I have since reattached the air intake and drove it around for a while got gas did a few things and had no starting issues since but am scared to drive the car anywhere publicly at this point as it has stopped on me about four times so far.

Also read up on the cam position sensor. I replaced all 3 (there were two of one and one of the other but I cannot recall which was cam or crank) on a BMW for maintenance and starting issues on high mileage. Expensive but fixed it.

I had this issue with my 2004 Infiniti M45 at around 200,000 miles. Crankshaft position sensor was the culprit. It was intermittent but progressively got worse. I ignored it the first & second time it happened. I was taking it to the dealer when the 3rd time happened and it wasn't fun... car crapped out in the middle of a large shopping mall....right dead center in the entrance drive. Eventually got the beast restarted and to the dealer. Sensor was replaced and the car's still happy to this day.
