What's the domain name? I suspect that the NS records in your zone don't match
what is in your delegation NS records, and that the zone NS records point to
non-working and/or unreachable nameservers (so the query always works the
*first* time, but when the leaf-node records time out of your cache, your
nameserver tries to refresh them from the non-working nameserver(s) and that's
where you're getting the timeout).
