MP10WES Shutting Down after 1 minute

I have a new to me MP10WES that I just installed in my tank. This is my second Ecotech MP10WES. Upon powering it up, it will run for about one minute before it shuts down entirely (no lights or blinking on the controller whatsoever). It will remain off until I pull out the plug and plug it back in again, upon which it will run for another minute before shutting down.

Any ideas what would cause this?
