What will make a car cut off but start right back up?

* Faulty fuel pump: A failing fuel pump can cause the car to cut off while driving, but it can start right back up.

* Clogged fuel filter: A clogged fuel filter can restrict fuel flow to the engine, causing the car to cut off. When the filter is cleared, the car can start again.

* Faulty ignition switch: A faulty ignition switch can interrupt the electrical connection between the battery and the starter, causing the car to cut off. When the switch is repaired or replaced, the car can start again.

* Loose or damaged battery cables: Loose or damaged battery cables can cause a poor electrical connection, leading to the car cutting off. Tightening or replacing the cables can resolve the issue.

* Faulty crankshaft position sensor: A faulty crankshaft position sensor can provide incorrect information to the engine's computer, leading to the car cutting off. Replacing the sensor can fix the problem.

* Vacuum leaks: Vacuum leaks in the engine's intake system can cause the air-fuel mixture to become too lean, leading to the car cutting off. Repairing the vacuum leak can resolve the issue.
