Does it only work right after you start a session and always stops
working after a few minutes or could it happen that it works for hours
and then stops to work?

Since it sometimes does work, the rules are likely ok, but you
anyway could check rules for auto-mounting, most likely pam is used

  grep mount /etc/pam.d/*

but maybe you need to care about udev

  ls -l /etc/udev/{,rules.d}

After it stopped working again I would check if polkitd is running

  pidof polkitd

and it might not be related, but you never know, check if the user has
got access to dconf. If you e.g. run a GNOMEish editor with root
privileges, it could happen that the user's dconf doesn't have user
privileges anymore

  ls -ld /run/user/$(id -u)/dconf/user

Is there anything related in log files? In
  
  less ~/.xsession-errors

or somewhere in /var/log/ ?
