What causes a engine to suddenly shut off even when vehicle is in motion?

An engine can suddenly shut off while in motion due to several reasons, including fuel supply issues, such as a clogged fuel filter or failing fuel pump, which prevent adequate fuel delivery. Electrical problems, like a faulty ignition switch or battery issues, can also lead to sudden shutdowns. Additionally, overheating or engine management system failures, such as a malfunctioning sensor, may trigger a safety shutdown to prevent damage. Regular maintenance can help prevent these issues.
