[nafex] Grape stems dead?

Folks,

Anyone know what's eating my grape vines?

I have six vines. Two of them had the issue shown in the photos. The
bark at the bottom of the vine is gone, leaving a bare stem. The bark
above that point seems sort of misshapen.

One of the affected plants had leaves that were fine all season but now
the vine has broken off at the base. The other plant lost its leaves but
the vine is still attached.

I've included some close-ups of the bark.

Please help! Is this animal damage? Sun damage (I'm in New Mexico and
the sun is quite strong.) Some bacteria or virus? And what do I do?
Assuming I get some shoots from the roots, are they infected? Is this
going to get my other grapes??
