If it continues to power down you could attach a serial cable to the mcu serial port and try to capture what's going on.

Hope its not overheating already. It gets quite sticky in Auckland in February, that's when I was always most worried about my A1XE.
When the temperature is critical high and the mcu shuts down the computer you will see it on the serial log.
I learned that when i somehow managed to stop the cpu-fan from spinning and the system was shut down
That was when i was still testing different fan configurations in the case so i always had a raspberry pi connected to it so that i could see if my experiments did any improvements to the cooling.
I also suffered from random shutdowns later on when i did not have anything connected to the serial so i did not know why it was shutdown.
It got worse and worse and eventually it would shut down just after powering it on so i had to investigate it.
That situation was cured when i replaced the mmc card so i guess it was corrupt or had a bad connection (i reflashed the mmc card so it was too late to investigate it further).
