I uninstalled Chrome, rebooted my machine and then reinstalled Chrome. I logged into a few sites and then rebooted only to see my passwords were wiped out again.
Microsoft? Anything?
Try logging in to your Google account and make sure sync is turned on and see if they come back. That worked with me but I completely uninstalled Chrome as I do not trust Google especially since you have to sign in to see saved passwords and saved sites.
