You will probably need to use a serial console to connect to the system
and capture any output.  See:

	http://www.tldp.org/HOWTO/Remote-Serial-Console-HOWTO/

and you may want to make grub use the serial console as well:

If you are using the system when this occurs then rebooting and looking
is /var/log/messages for entries around the time of the problem may
help.

This sort of question is not appropriate for the Fedora Development
List.  You would be better asking on the Fedora List:
