Node failing, surges?

This is not bashing the product which I enjoy and have other units elsewhere. I have this unit in CO and after 11 mos it simply failed to power up anymore. It was replaced under warranty. Used the new one for 2 weeks and seems like the same issue where it simply shut off and that was it. There was some lightning the second time.

All the stereo electronics are hooked up thru Panamax Max 5100 power conditioner and surge protector. There was no pop, click or anythin when this unit powered off. All other components are fine and kept running. In fact in 20 years never had a power surge take anything out here. The only other thing I can think of it I have Ethernet hard wired into this node and that Ethernet switch is on a different surge protector device. So not clue if I could be a power surge, something thru Ethernet, or something else. 
 

I have started a ticket with bluesound but figured I would see if anyone had any ideas as besides the loss want to try to ensure it does not happen again. Thanks.
