I just typed a detailed answer to this person'* question and then it disappeared.
My car was stalling and it turned out to be the crankshaft positioning sensor working intermittently I guess because supposedly if it fails the engine will not start.
One way I read to test the sensor is to pour a gallon of water on it after the engine stalls and if it starts up right away (instead of waiting the usual 5 - 7 minutes) that could be the problem.
There was no code for it on my car, which I found out by doing some internet searches.
If it'* this type, then be sure it is installed in the exact position it was in before removal.
I can share a lot more, but don't have the half hour it took to type in all the details the first time around.
