Intermittent internet connection on SB8200

So I was using my internet as normal when I all of a sudden lose connection, look over at my modem and it is power cycling, first power lights comes on, all lights under light up and then they all turn off and it repeats. I don’t have any extra power cables for this so I tried the one from my Phillips hue bridge and same thing. I’ve tried to unplug the modem from the wall, tried a new outlet, kept it unplugged for some time and replugged back in, I’ve also tried the reset button on the back which is when the original power cable stopped working completely. Is this just an issue where I need a new power source or is this thing messed up? I work overnight and need to be on ASAP but can’t figure it out.
