Atem Mini Extreme ISO randomly stops recording

I've had my extreme for a week or so, but just trying to do my first recording, and it's very frustrating. I have it set to record ISOs, I have a USB-C SSD attached to the ATEM, and after about 10 minutes or so of recording, it just stops!?!?
I have plenty of capacity left on the drive. I've tried both a Samsung T5 1 TB drive, a Sandisk Extreme 2TB, and a Sandisk Extreme Pro 1TB. All three just randomly stop recording after 5-10 minutes. Any ideas what might be wrong and/or how I can troubleshoot?
The ATEM (via multiview) shows plenty of capacity on each of the drives. The drives do record the program and ISO output until it stops.
I was looking to put a video down today, and am totally bummed I can get it working. Thanks for any help!
