Dying Thunderbolt port?

Dying Thunderbolt port?
I've been having a devil of a time with my Mini disappearing from Dashboard, Finder, and Disk Utility.

It's been reliably connected to my iMac for quite some time but it's now just dropping with alarming regularity, and I can't seem to get it to connect today.

I have tried switching the Thunderbolt ports on both the iMac and the back of the mini, and I have tried both Thunderbolt ports on a MacBook Pro - but I simply can't get it to mount.

The disks all appear good (based on the green lights on the front) and no amount of reboots to the mini itself or either computer seem to matter.

I do have another drive connected to the Thunderbolt ports on the iMac, and it does work on both ports and is not dropping, so I am 99.999% sure it's the Thunderbolt port on the Mini.

I suppose it could be the cable too, because that's the only other consistent piece of hardware, but seems like a long shot for a cable to flake out and "die" but there are active circuits in there, so maybe?

I have updated the dashboard on both iMac and MBP to 3.0.1, and both are up to date in Sierra (the iMac is on 10.12.4 beta 7 and the MBP on 10.12.3 stable)

Any other ideas?

EDIT - I realized I still had the USB3 cable that came with the Mini, plugged it in and it fired right up. So either it's the Thunderbolt controller on the mini chassis or it's the cable. I'm going to keep it on the USB cable for awhile and see if it's stable before I try a new Thunderbolt cable
