Loss of power engine cut out sputtering?

Loss of power in an engine, accompanied by sputtering, can indicate several issues. Common causes include fuel delivery problems, such as a clogged fuel filter or failing fuel pump, which restrict the flow of fuel to the engine. Ignition system issues, like faulty spark plugs or ignition coils, can also lead to misfires and sputtering. Additionally, air intake problems, such as a dirty air filter or malfunctioning mass airflow sensor, may contribute to the engine's poor performance.
