Hi Matthew,
I suppose that you have tried to switch between the ASCOM and native driver?
Other idea is to try to make a USB2.0 connection at higher speed. From all the feedback I have with ZWO, QHY and Altair Astro cameras this is common problem with the CMOS models. Quite random and hard to reproduce. My opinion it is caused hiccup of the USB connection that can caused by ambient temperature and/or humidity and/or cooling. I don't remember to see such behavior with un-cooled camera.
Sometimes changing the USB cable/hub works in other doesn't
I'm sorry that am quite fuzzy, but this is the information I have...
