This morning I came out to my car still charging, but reporting "APS output 2 (PEM) reset" on the touchscreen.

Does anyone have any idea what that means?

I am starting to get a little worried as this is the second glitch in as many days - 2 days ago I found the charging port lit red and "Charging stopped" reported on the touchscreen.
 
APS is the Auxiliary Power System - it provides 12volt power to a number of subsystems of the car. The message would seem to indicate something related to the PEM reset. Just guessing, and I think the only people who will know for sure would be Tesla.
