Printer beeps and shuts off
I just got my MK3s assembled, but I'm having a weird issue, and I'm not sure whether it's the electronics or something else. The printer passes its self-test and calibration successfully, and the first print (the Prusa logo that shipped on the SD card) went great. However, I'm trying to print a Benchy I sliced and I'm running into problems.
Every so often (maybe every ~10 minutes or so) during the print, the printer will beep once loudly and power off. If I turn off the power switch, then turn it back on, it'll detect the loss of power and resume the print. My initial guess was a thermal issue, but I measured the external temperature of the power supply and controller board with both my hand and an IR thermometer, and neither seem much more than "warm."
Is there any assembly mistake I might have made that's causing this without making the printer fail its self-test?

On the Prusa website, the store section, when you log in, there is a CHAT window that can connect you with Prusa support.
