1998 Dodge Neon Dies while driving

I have a 1998 Neon that keeps dying in the middle of the road. There is no warning such as bucking or hesitation, it just dies. I read as many articles as I could about the car and thought I'd just start with the biggest part first, I replaced the PCM. It started right up but then died trying to back out of the driveway and wouldn't start again. Ocassionally it will restart in 2 - 10 minutes and drive another short distance. I tested for spark right after it died and it was fine. I also tested the fuel pressure right after it died and it was fine. 49 while runnung and 46 after stall but held steady. I am now thinking about replacing the Cam and Crank sensors, any ideas as to how I should proceed? I checked the codes in the computer after the stall and received a code 12 as the only trouble. It tends to die when I hit a bump, go around a corner, or apply my brakes. No one more than the others but those are the times it usually happens.
Another interesting thing just happened. I got it running and tried wiggling the pcm to see if it would cut out and it didn't but when I dropped the hood shut and it slammed, the car died. Hope all of these little quirks help us get somewhere.
