Why does my car die while driving

Hello, There are many causes for stalling, and they can all be diagnosed and corrected. From a diagnostic standpoint, stalling is not the concern, the concern is that it stalls and fails to restart intermittently. In order for even the most skilled technician to diagnose the vehicle, it has to stall while they have the vehicle. Here is my advice: either leave it with a shop for as long as they need to replicate the issue, or start documenting the exact conditions required to make it stall. The third option is to just continue driving it until the time it stalls and refuses to restart permanently. I know this is frustrating, but there isn't much more you can do. It has to mess up while a technician has it to fix it, or they have to know exactly how to get it to stall.
