Google cloud has a session timeout across the board of 10 minutes, so you need to use a keepalive. Try adding the argument --ssh-flag="-ServerAliveInterval=30" - any value less than 600 should do the trick there.

There's a description of the timeout here, and full usage details for gcloud ssh here.
