LG fridge - Have power but board keep powering off

Hello - My LG lost power last night. When I open the freezer though the light is still on in there but the entire outside panel is off and there is no longer any cooling. I can unplug it and plug it back in, and then the panel comes back on for a few minutes, it starts to cool again, but then the panel goes off again and the unit shuts back off. Any idea what the issue is with my LG LRSC26923TT? Thank you.
