Random Engine Shut Off

Ok so to cover the basics, i have a 2012 jk 2 door with 56,000 miles. lift tires all that fun stuff. i have not done anything to the engine. so when im driving down the road the engine randomly cuts off and the immediately starts back up again. everything electric stays on, ac (when im using it) gets hot then after a second everything is back to normal. also headlights wont go into high beam, feel like they are somehow related. this normaly happens around 2,000 rpm goin down the road, but has also happened right after i start the jeep and in idle..... does anyone have any ideas what this might be haha. o and i have good fuel in the engine.

Check that battery cables are tight, charging voltage is good. Also see if there are any stored codes.

Cables are nice and tight and no codes are showing. did it twice because my buddy didnt believe me lol. i know a guy with a reader so im going to take it to his house tonight
