Decklink MiniMonitor 4K - Win10 - Premiere v13 Issues

Basically, with a 24p HD sequence, playback works fine for a few minutes and then the Decklink output freezes. Soon after that, Premiere will lock up entirely.

When the DeckLink SDI freezes I can still reposition the playhead anywhere in the timeline which updates the image in Premiere's program Monitor, but the original frozen frame remains on the DeckLink output. I also can't play video. Spacebar playback will not work. Sometimes I can hear the audio playing. Media files are 10-bit and 8-bit from GH5.

Once the Decklink output locks up I can still save the project, but Premiere will not shut down gracefully. Task manager > end task will close some Premiere threads, but one premiere.exe task always remains. Even shutting down Windows will not clear the freeze frame on the DeckLink output. The only way is to reboot using the PC's reset button or cycling the power supply.

I can't see any unusual CPU/Memory activity in in Task Manager.

If I disable the DeckLink in Preferences/Playback, Premiere works great.

I've tried 10.11.2 and 10.11.4 Desktop Video installations. I have a support ticket open with BMD.

BMD says they cannot reproduce the problem.

I have tried super-basic Premiere sequences and even reverting back to older DesktopVideo driver installations without luck.

I don't think it's a Premiere issue. I can shutdown Windows completely and the Decklink card continues to output the frozen frame to the SDI monitor. The only way to clear the output is to cycle the PC's power supply.
