So I have a 2012 jk that for some reason will just loose all power. This only happens while I am not driving it thank god. Like today for instance, went to a local store and came out to no power at all. No lights or locks or anything. I just chilled in the jeep for 5 mins and then tried again. Then everything works like nothing was wrong. No jump or anything. It does not do this all the time, maybe once a week. I do have some lights on the jeep but I am 100% sure I wired everything correct. Not sure what's causing this at all, any thoughts.

 

Did you look at the battery cables? Maybe they could be loose, I would start there.

 

Check all the ground connections.
