It is not your TTL values that is the problem it is the EXPIRE value.
TTL is used for the caching of the information and tells the cache when to
remove the information.
EXPIRE is the value that tell the slave how long the information it the zone
file is good for when the master cannot be reached.
Leave your TTL at 300 (5 min) and change the EXPIRE value to something like a
week or more.
