Airbus lost all power on approach

[lrc 4]

So, I was flying the Airbus 320 from KCVG (Cincinnati, Ohio) to KATL (Atlanta, Ga) High altitude IFR.  All went fine until about 10 miles from KATL, and the plane just went dark. All instruments went black and I lost all power.  Needless to say, it was a crash and burn.  Any ideas what might have happened?

Asobo bus or FlyByWire?

If the later, there was a bug in their discord about double engine flameouts. I'm not sure if it had anything to do with accidentally nudging your flight yoke mixture lever or not, but if you have discord it's worth a shot asking them there so that you can avoid this issue in the future.

The batteries don't need fuel.

Running out of fuel was my first thought, but I should still have electrical power I would think.  Everything went black.    Thanks for the replies.

WestAir, it was the default airbus in MS 2020

Did the RAT deploy?

Virtual-Chris. No, the  RAT did not deploy. I was on final, about to catch the glide scope. When everything went dark, nothing came back on.  I sunk like a brick.
