It sounds like you are running some web application that is hanging ever so
often.
Hangs cannot be correctly detected 100% of the time, and since nothing
crashed and IIS is just hosting your web application, you are not going to
see errors recorded anywhere. IIS simply cannot figure out that "something
is wrong" in the hosting process if the web application doesn't complain.
It sounds like you need to run a tool like IIS State on the inetinfo.exe (if
low isolation) or dllhost.exe (medium/high isolation) that is handling your
URL WHEN the website is not accessible, to see what is getting hung up and
troubleshoot from there.

I wish I have more error message to give you. There is no error in the event
logs, both system and application. Since this issue is intermittent, there
is
no pattern. Our NOC calls us whenever users call them up to complain the
website is inaccessible. I can login to the server also can telnet to port
80. Even restarting website won't bring the site back. But after restarting
IIS everything is normal. Is there any debugging tools I can install to
debug
this issue.
