If its not an ACL issue, make sure you configured 'login local' on your VTY lines to make use of the local database when connecting in
Check also that you have not disabled SSH access into your VTY lines using the transport command.
Make sure 'transport input ssh telnet' or 'transport input telnet ssh' has been configured
Failing all that it could be an exec-timeout issue, maybe that has been set to low and its automatically logging you out, although this is more unlikely based on your report.
