First thing I would look at is, do all of your DNS servers reliably return the same results? If you have 3-4 DNS servers and one of them doesn't return the right info, this could conceivably cause what you are seeing.
One other thought, beyond what Al said... Any chance you've started delivering to Google via IPv6, but your SPF only covers your IPv4 IP space?
