Trees, Shrubs and Conifers: Almost dead pinus parviflora, 1 by Weerobin

What's up with my poor nearly departed pinus parviflora?
All the limbs abruptly turned brown except a single limb.
The strange thing is that the surviving limb is sandwiched between dead limbs.
I presume the tree is going to go ahead and die, but it's been a month since the other limbs browned,
and yet the single remaining green limb is still green.
Anyone know what's happening here?
(Not the greatest photo, but I think you can see the problem.)
