Default Stalling 850

Hey guys.
I have been having a problem with my car a few weeks now. It stalled out a couple of times on me. I took it to one mechanic and her changed the coil module(if that is the correct name). but the was not the problem. I took it to Ammco and they did a complete diagnostic on it and the onlt thing they found was the transmission fluid was burnt and the the tranny was not functioning properly. so i changed the tranny and I still ahve the same problem. Most times when it stalls I just put the car in park or neutral and start it up and it goes like nothing happened.
Can it be an electrical problem or it is just not getting the fuel properly.
Any help on finding my problem would be very much appreciated

It could be many things. The first to look at is the fuel pump relay,Cam sensor, and PNP switch.

The PNP switch is under the battery tray on the transmission. Where the cable attaches to the trans. The sensor is on the shaft.

Looking forward to the results here. I am having the same problem and interesting enough it started about the same time as yours. Once mine stalls I have to wait about 10 minutes before it will start up again.
