My car randomly shuts off while driving it. All lights stay on when key is out.

If i tirn key off when engines running, yes it shuts off. It runs great and lights work correctly when engine is working. When it just shuts off while driving, thats when lights wont go off. Ive shut down everytim when it was dark out. Otherday it shut down again while it was light out. I didnt notice any lights on so i did not unhook battery. Later when it got dark out, my neighbor knocked on my door to tell me my headlights were on! The KEY WASNT IN THE IGNITION!!! OMG. I cant take this anymore. Whats wrong with it. Why wont it start now. And why are lights connected to this problem

Hello, Sorry for the late reply, the issue is likely with your ignition switch, or bad relays. When your vehicle acts as if the key is turned to "ON", but the key is out, the very first thing I would check is the electronic portion of the ignition switch. The vehicle will not start because the headlights drained the battery, the ignition switch is not activating the systems it should, or both. Look at the links on the screen to find a shop in your area for diagnostics, as the ignition switch is likely bad, but this has not been proven.
