Could something be overheating?  You could perhaps try putting the
external drive in the refrigerator for a few minutes, but not long enough
that condensation can become a problem.  Then take it out and see if it works
any longer.  It is an external disk, after all.

Of course it could be another part overheating, such as the USB interface
inside the computer, which is harder to refrigerate.

I had problems like this with a video card a while ago.  It turned out
that one of the cooling fans was clogged with dust and not turning.
