Delta 2 stops DC Output Randomly

Howdy all. Brand new Delta 2 (less than 24 hours) is having an issue not covered in the manual.

Yes, I've reached out to customer support. Just curious if anyone has come across this before.

The delta 2 is powering a camping fridge. At any given moment it will pull between 55 and 85W. It can run for 20 minutes or multiple hours before it has the issue.

Because of the randomness its hard to film. What you see attached is the second half of my description below:

I hear a click (which I assume is the dc output turning off because the fridge turns off at this time), the delta 2 beeps, then the red battery icon on the delta 2 flashes twice as well as the remaining life and SOC. Video is of the second flash. It's all done and dusted in about 5 seconds.

The fridge works fine, and is currently plugged into an AC outlet of my house without issue. Next step is to plug into the AC of the Delta.

Thoughts?
