Q: Full system failure and no power to the vehicle

asked by on January 16, 2017

While driving a few days ago, my engine suddenly stalled without warning, and all the electronics failed with it, even down to the power door locks. The car acted as though both the battery and alternator had been removed. About 30 seconds later everything started up again and worked perfectly fine. This has happened two more times over the past couple days with no apparent pattern.
