Why my car shuts off while driving and then turns back on?

There are a few reasons why your car might shut off while driving and then turn back on. It could be a problem with the fuel system, the ignition system, or a sensor. If the problem is with the fuel system, it could be a clogged fuel filter or a bad fuel pump. If the problem is with the ignition system, it could be a bad ignition coil or spark plugs. If the problem is with a sensor, it could be a bad oxygen sensor or coolant temperature sensor. To figure out what is causing the problem, you will need to have the car diagnosed by a mechanic.
