Your car seems to be showing symptoms similar to a vehicle with a dirty or failing idle air control valve. This valve regulates airflow when the throttle plate is closed, and if clogged, you will have to usually keep the engine alive by adding throttle input. It may work cold, but when the engine demands more air, and if the valve is stuck, it can stall the engine. Have a professional from YourMechanic come and inspect the stalling issue in person and make the correct repairs.
