Can somebody see what I could possibly be doing wrong with my pool?

My hasrate is about 450GH/s

My a week ago I rebooted my pool and added a local 350Gh/s BF rig.
For the first 24/hr I got 3 dead shares.
So I rebooted the PC and it started working fine.
As you can see from the payout of the pool I was getting .009xxx a block.
Then the payout switched to just under .004xxx with no noticeable pool hashrate increase.
Now I noticed: "Payout if a block were found NOW: 0 BTC" and my last 2 blocks were dead also.

My config is running on a Windows 2008 R2 server that is on a private fiber line.
I setup pool based on the http://p2pool.in/ information.

What could I be missing?

Thanks
