This started happening to me. I recently changed my oil and both of the belts. Whenever i come to a stop it just dies. But turn on without a problem. Theres also this high pitch humming noise that sounds like its coming from the belt area or under it an a slight smell of like burning metal or transmission oil or something. Maybe i put too much oil or the belts are ****. Idk help

 

You should probably just take the car in for a 1 hour diagnostic before it ends up costing you a LOT.
