perhaps - but unlikely.

by default, there are heartbeat messages every 10 seconds between the cache
and the router --
if 3 of them are lost, and the router subsequently sends out 3 query
messages 1 second apart, and they too aren't answered, then the router will
remove the cache.

you should really look into why the router is at a high cpu utilisation.
ie. what is it doing to cause the high cpu utilisation?

it sounds like a possible bug in the wccp implementation for squid.

if you run IOS 12.0T (eg. 12.0(7)T), it will syslog "cache acquired" and
"cache lost" messages when caches appear/disappear - telling you why.
