Having the same issue with my 2014 LTZ, i had it jumped once last week, died on my this week as well, so i popped the hood to check it out, its a wiring issues definitely. All i did was wiggle the negative (black) wire leading to the battery and the car lit right back up, drove home no issues, it seems to be an ez fix but annoying if i gotta do this every week. Plan to take it to shop on tuesday, but hope this advice helps in meantime.
