I had this same issue. I found it was a heat issue. I put a 1RU fan mounted directly above the ATEM and it has never done it ever again.
I also saw someone mention that the ATEM dissipates heat down the cables, so even if you arent using the inputs or outputs, hook cables to as many ports as possible. I have expanded my system since iput the fan in, using almost every port, and i have never had any of these issues since.
