Weird random problem

Ok guys something is off dont know what is going on ZERO codes stored. Havent made any changes to the car and its running great i have just done routine maintance. But heres the problem sometimes when coming to a stop or while stop random out of the blue the car will be running fine an then bam just turns off like i turned the key off. I put it in gear and starts right back up and runs fine. I have checked for leaks an such an nothing seems amiss. Its weird cus theres no codes 12.06 voltage off and over 14 while running. Its weird cus its random, it starts right up , and runs just fine afterward. Theres nothing that happens before it stalls itll be running perfect just happens and always starts right back up.

checked your fuel pump fuse in trunk to ensure no corrosion on contacts of the fuse?

Well new developement today i have school from 7am to 4pm today getting my BSN an then on to nurse anesthetist after so busy busy an i decided id do the crank sensor after school. Well as luck would have it i come out to go hm an car wont start turns over no start for over 2 hrs. So i call the tow truck an get hm sure as hell it fires right up to come off the trailer. But i finally had a code an sure as hell p0335 crank sensor. So i removed the old one took bout 20 mins was factory original 140k so bout time an installed the new bosch one an fires right up gunna go play with it for a bit an see how she does. Thanks guys ill keep u all updated if anything changes but knock on wood seems like this was my culprit.
