@bshah - Thanks for the suggestions here. I updated the firmware and restarted Stretch. I still observe intermittent disconnections.

Here is the exact error I get:

ERROR: The device has been disconnected!

An exception has been thrown: xioctl(VIDIOC_S_FMT) failed, errno=5 Last Error: Input/output error
.

Hardware Notification:IR stream start failure, 1.67847e+12,Error,Hardware Error

Here are the details from rs-enumerate-devices:
