MCU went blank while driving - now when starting

I've had a look, but only see old threads on this.
Running 2018.28.5 377ec8b on a 2015 MS60 with AP1.
My wife was driving on the highway a couple of weeks ago when the MCU went blank - no warning, just blank.
Continued drive, parked, went back to car - all fine.
Today she arrived at destination, got back in car - MCU blank.
Vehicle (apparently) safely driveable both times.
We have not seen this before with more than 20K miles on it - is this symptomatic of any failures or just bugs in the latest software?

Happened to me also while on a trip. Came back on its own in a few seconds.
 
MCU, not IC, going blank is often a sign of the eMMC memory in it going bad. Eventually the MCU will stop booting and it will cause charging problems, as well as the inability to control anything from the screen.
