It is better to fix it so it works in crontab than to use sleep and at(1).
What problems do you have with crontab? Did you remember that your shell environment is limited?

while true; do
h=$(service httpd status | awk '{print $3}')
if [ "$h" = "stopped" ]; then
service httpd start
fi
sleep $(( 5 * 60 ))
done

(Assuming that the calls to service don't take any time.)

adding to Mr. Dennis, run the script using at command. or use nohup before the script name.

e.g
nohup ksh /tmp/scp.txt &
