Hello, typically when this happens the engine is protecting itself from further damage due to a concern that is happening actively. Hands on testing is needed - checking for diagnostic trouble codes in the engine's processor by using a diagnostic tool to inspect it, and then also checking critical areas such as throttle control, engine temperature control and automatic transmission operation.
