Wow what a roller coaster of troubleshooting this was.

I thought I had the issue resolved, and last night it started resetting on its own again.

I'll spare everyone the long troubleshooting story again, but turns out my PoE Splitter for the PI was also toast. The switch ports are acting funny (not giving full speed anymore) and the PoE Splitter smelt like burn electrical when I took it out.

I'm now using a Ubiquiti PoE injector and replaced the PoE splitter with a spare 100mbps version I had, and it seems the issues are good.

Time will tell for sure.....

rpi voltage expectations finicky at high current draw

Reducing your convoluted fun RPi prefers voltage at the top end of the spec

5.25 volts at whatever amps it wants. You can either use one of the inexpensive buck/boost converters on ebay/amazon or find the 5.25 volt usb power supply options on amazon. ~ $8 USD to $25 USD for these items.
