When dnsmasq is running I have a constant load on my router processor of about 20-50%. Additionally, there is a constant download load on my WAN of about 8-12 Mbps ( I have a 20 Mbps Internet connection).

It sounds as if there is another computer (possibly unauthorized) on
your network which is generating the traffic.  Since you aren't
putting a static IP or DNS configuration on that other computer,
wherever it may be, it doesn't work when dnsmasq isn't running.  But
the problem is not dnsmasq itself.
