Ok, here is an update: I figured out why the car was not starting properly and that was the OVP being loose from the its harness. The car started right up after I took care of that issue but that didn't solve the stalling issue at a stop.
I went ahead this morning and swapped in a crank position sensor that I pulled from another car just to see if that would make a difference; nope! I am still having the same issue where the car stalls at a stop.
The stalling comes in different flavors where sometimes the rpm surges a bit, sometimes it simply drops to 500 or the rpm start fluctuating up and down with the oil pressure doing the same; all these observations are right before the car stalls, it all depends what the car feels like throwing at me.
I did hear some sort of relay clicking in one of my stalling sagas. It sounded like it was on my left side near the speaker. As soon as I heard it click the car went dead.
