car dies while driving · engine shuts off randomly
The engine unexpectedly shuts off entirely, either while idling (at a stop) or, more seriously, while actively driving.
Note the exact conditions when it stalls (idle only, while braking, at speed, when hot vs cold) - this pattern is very useful information for a mechanic.
Not recommended, especially if it has stalled while actively driving. This can happen again at any moment, including in traffic, and can affect power steering/brake assist.
Describe your situation more precisely (e.g. exactly when it gets worse, how long it lasts) and get an expanded, personalized breakdown.
