S19J Pro keeps shutting off - Need some help!

I have 2 s19J Pro's currently running in a very clean and virtually dust free environment. They both have their own dedicated line and each is hooked up to a 20amp Triplite Strip that is only for each unit. One of the miners is working and running just fine. The other however started being a bit temperamental about a month ago. The unit will just randomly turn off. I didn't know if it was shutting down due to temp or safety, but if I unplug the wires and plug them back in, the unit fires back up. If I leave the wires plugged in and just hit the reset button on the strip, the unit fires back up and runs for about 1-2 days and then it turns back off. No issues with connecting to the pool or mining while the unit is running.

The boards are about as clean as the day I got them and the units have been running for about 3-4 months with no issues until now, and it is just 1 unit.

Any help as to what I can do to get this fixed would be very much appreciated as I do not know how to do a diagnostic, and I would like to solve the issue and have the miners back up and running ASAP.

Thanks in advance!
