Here is the code to set the time out for the session. If you are not using state serve r(mode:InProc) then the session will get cleared when the web.config is changed or the browse cache is cleared(for firefox) and also Review the config settings also.

<configuration>
  <system.web>
     <sessionState mode="InProc" stateConnectionString="tcpip=127.0.0.1:42424" 
      sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes" 
      cookieless="false" timeout="20" /> 
  </system.web>
</configuration>
