WAN going DOWN and UP

Hi All,
OK bit of a long one perhaps, but I'll try to get as my details in here as possible in the hope you guys can advise:
I have an APU2c I bought from Appliance Shop EU, which has been running since July OPNsense. The LAN port is connected to a TP-Link gigabit switch, and the WAN is connected to an Arris cable modem in bridge mode.
The other day the internet started playing up, and while I thought it was my ISP, after digging around a little I realised it was actually the OPNsense box. I see the following in /var/log/system.log

Dec 18 06:20:10 gw kernel: igb1: link state changed to UP
This repeats constantly until a reboot. The odd thing is it can go anything from 5 minutes until 11 hours without failing, then suddenly again it begins.
To check it was not the ISP, I spoofed the OPNsense MAC address to a MacBook Pro and connected from the Arris directly to the MacBook Pro, and the connection is solid, no ping drops. If I then reattach the cable to the OPNsense it immediately continues sending the WAN interface UP and DOWN once again.
The only thing I do notice in the logs is a line like:
Dec 18 07:47:07 gw kernel: amdtemp0: <AMD CPU On-Die Thermal Sensors> on hostb5
I've tried swapping cables, rebooting the Arris, everything... I'm torn between if this is a HW or SW issue. I've looked at top output when it's been happening and not seen any problem processes.
So, your thoughts please guys?
All the best,

Well, I decided to purchase another power supply. When the problem was happening I swapped the supply for the new one, and now 24 hours later no issues... so fingers crossed that was the issue.
If not, I'll be back here.
Thanks to the #OPNsense channel and to Appliance Shop for their help on IRC.
All the best for Christmas and New Year.
