Have you by chance checked your NAT through the Xbox Live Connection Test? Often times if you have a Moderate or worse NAT it can slow down your connection with Live and can result in lagging and being bumped from games ultimately. This happened to me once before; so I checked my connection and my NAT was at Strict :S. I messed around with my router and it returned to open.
I'm not sure if this is your case, but it wouldn't hurt to check your Internet Connection and NAT. Another factor would be if there's a lot of people using the internet at your house at once.
