DEC recently sold off their magnetic media division to Quantum.  The
unit you have was made by Digital before that took place.

Are you 100% sure?  Have you tried swapping SCSI/power cable heads, or
even replacing the cables completely?

If you've tried the above it sounds like it's overheating... usually a
sign of it's imminent death.

I had one of these a year or so ago and it failed in EXACTLY the same
manner.  Powering down and leaving it for an hour or so would
generally get it back (for a while) but the time taken to "recover"
gradually got longer and the running time reduced until the drive
enventually died completey.

My advice would be to get anything you want off the drive and throw it
in the bin.  If you MUST continue to use the unit, backup regularly
and don't put anything critical on it.
