What causes an automatic engine to stall?

An automatic engine can stall due to several factors, including a sudden loss of power from the engine, fuel delivery issues, or electrical problems. Common causes include a faulty fuel pump, clogged fuel filter, or issues with the ignition system. Additionally, a malfunctioning sensor, such as the throttle position sensor or mass airflow sensor, can disrupt the engine's performance and lead to stalling. Lastly, low levels of Transmission Fluid or issues with the torque converter may also contribute to stalling in automatic vehicles.
