Are you using session variables in those pages? If you are, your session is
timing out, please check to see that you havent changed the timeout setting
anywhere in your code. If thats not the case. Open the EventLog and see if
theres any message saying aspnet_wp.exe getting recycled. If worker process
gets recycled, you lose all the session data too. So, please check the event
log for any error messages

We get " Object reference not set to an instance of an object. "
error in all the links whenever the browser is not used for more than 5
minutes.
In IIS 5.0 version we are setting the session time out to 60 minutes.
Please let me the know solution if any knows the answer.
Thanks
