OK I think I just gave myself a headache.
I've been researching for a few hours due to the rain preventing me from working on the Jeep much today, and some info I have been reading is confusing.
The Crank Position sensor is on the bell housing right? and the CAMshaft sensor is on the distributor right?
From what I gather, they work together... but, if the CAM position sensor was going bad, would it cause the engine to shutdown while driving as well? Because from what I read, if the cam pos sensor craps out, then it wouldn't start at all, so should I just keep with the speculation that its the Crank sensor thats the issue? Because whatever it is, it's intermittent, and I'm thinking it could possibly be thermal failure of the part.
I checked the alt and battery right before it rained and they are fine. I also checked the feed wire to the PDC as 5-90 suggested, and it looked good, and wiggling it around had no effect.
However, I did find the connector for the Crank sensor rests just below the oil tube, and it was covered in oil, so I unpluged it, and found oil inside.... I sprayed both ends generously with carb cleaner and then blew them out with my compressor. I'm going to take it for a test drive in a few hours to the store and have my uncle follow me just in case.. but I'm doubtful cleaning the connector solved it.
