Q: Why does my car keep stalling?

asked by on

Whenever I drive a long period of time my car stalls. Once I put it in park it will start again. I took it to the shop but they couldn't find what's wrong with it or why it's stalling.

My car has 140000 miles.
My car has an automatic transmission.

You did not state the engine you have, but I would suspect that you have a problem with the ignition system since the vehicle restarts again after cooling a few minutes. A scan of the computer may show a problem with the ignition module or coil. These two are the most common cause of ignition failures and this is only a place to start. If you want to have this diagnosed by a professional, a technician from YourMechanic can inspect your stalling issue and perform any needed repairs.
