Air intake sensor. It's on intake manifold on cold air input. If the sensor get dirty or corrupt ( bug, dirt, misc) will affect timing and intake airflow to the motor causing it to sputter and possibly stall. It may or may not be some part you can get to depending on your experience but check this ...95% of the time this is what craps out on most cars and sport utilities..mass air flow sensor
