How long did it take?
Having the logs for all servers (for both cases: for when the elections
fails and for when it succeeds) would be helpful. Please paste the logs on
gist.github.com or something similar since reading them in-line is a bit
hard.
I don't think the unclean shutdowns should be a problem, as long as quorum
can be formed (i.e.: they'll just be ignored, since ZooKeeper is meant to
be crash safe) (also, a Windows shutdown is probably not very different
then a shutdown through the init scripts).
