After about ten minutes of running, my headlight will go off without warning. Have to shut off for a few minutes then it will come back on, only too go off again at some undisclosed time. Need help

What type of car is this on? In some cars and jeeps if you turn off the headlights after the ignition is off the lights stay on for 10 minutes. Its possible if yours does that you have either a disconnect somewhere or the stitch itself is bad. Only operating in AUX mode.
