RAX54 v1.0 - Constant Crashing

As the title states, my router is constantly crashing.  First the GUI fails and then shortly there after, the whole of the router fails.   I have to manually restart the router for it to work again.  It can take anywhere from 2 minutes to 30 minutes for the GUI to fail, and after the GUI fails the router can fail anywhere between that time and about 2 hours.  I am unable to gather logs due to the fact the router is failing and has to be restarted, or the GUI portion just does not work.  I have tried routerlogin.com/net, the IP address, the app.  I have tried calling tech support but they insist I pay a fee to figure out why their router is failing.  To me this seems like a hardware issue. So before I return this thing to Costco, I was hoping someone here has seen this issue, and knows how to fix it.  Any recommendations are welcomed.

I have tried:

• 30-30-30
• The three latest firmwares, in different order so I can upgrade/downgrade from different firmware.
• Manually setting up the router.
• Using a config to set up the router.
