What might cause a switch to STOP.?

Let me explain
We have a new (2 month since we purchased) WS3 switch. Its been in production at a tower for about 5 weeks. Its a DC switch serving only 24v to POE AP's mostly Ubiquiti and Cambium. DC is supplied from a ICT modular serving 56v. It has been working perfectly, then one saturday at 3am, it stopped. When I got on site the power light was off, fans off, no LED's anywhere. Voltage perfect at the terminals. Power cycle got a green power light and fans, but it shut down after about 90 seconds. No ammoiunt of power cycle, waiting for 30 min, then power up, changing DC circuits, nothing got the switch running. We swapped it for a Mikrotik because we need to service our customers. Brought it back to the shop and before we RMA'd it I decided to pwoer it up, and it came up. I reset it to factory and its working fine. I left it on for a day and it still works. But I am NOT putting it in production until I understand why this would happen.
So, thats the question, what would cause a switch like this to bork so badly, then come back to life???
I appreciate your attention to this matter.......
