What conditions cause the frunk and/or roof power feed to turn off.

I run a little power station in the frunk which runs my fridge. This charges off the frunk power supply on an xt60.
I have noticed that this feed will stay on if turned on at the screen even if the car turns off and also while level 2 charging. The vast majority of the time this keeps my power station topped up nicely.
Occasionally though, I’ll come back to the truck and it’s turned off for some reason.. There doesn’t seem to be any rhyme or reason to it.
Can any of you help me understand how this works? Does it turn off when the car goes into a certain type of sleep mode or what?

I haven't figured out out yet. I installed a xkglow light bar and leave it powered on for the DRL mode. I've left it on for 12 hours parked in my driveway and it stays on. I've tried charging and unplugged.

Same. My frunk supply stays on even when the “keep outlets on” and “keep aux power on” are not menu enabled as long as the frunk power source is left on under outlets and mods.
Then occasionally it seemingly randomly turns off. As you mentioned, it’s not from charge port use and in my case has not been related to low battery state. My car almost never gets to or near 20% unless I’m on a road trip.
It’s also not draw/idle because the power bank draws continuously. I’m thinking it might be related to the car going into sleep mode but was hoping someone here has more than just a guess.
