Default Dashboard/AC Turns Off at Stop while Engine Runs

I have a 2012 S5 Coupe. For the first time ever today I had the same problem 3 times driving home from work.

If I was stopped at a red light etc for more than 15-20 seconds the dashboard lights all went out, the AC turned off, emergency lights didn't work, but the engine continued to run. I was still in drive but when I tried to give it gas the "Brake" light came on and I didn't want to mess anything up so I stopped. I guess it's some sort of emergency feature. Everything in the MMI seemed functional, but I was on the phone at the time so didn't navigate through different screens.

After putting the car in P and turning the engine off then on again I was able to drive fine.

Any idea what would cause this?

Possible wiring harness problem?

Sounds like the electronics got confused and was reset when you restarted. If it happens again then take it in to a shop
