Here's a simple shell script (run it under cron every minute or so) that checks to see whether Apache is still running and, if not, restarts it:

#!/bin/bash
if [! "$(/sbin/pidof httpd)" ]
then
apachectl start
fi

<edit>
Set your cronjob to email you the output so you know when Apache has been restarted.
