With a given hashrate your earnings depend on what fraction of the global hashrate yours is.
When the global hashrate increases (which it has, see http://www.coinwarz.com/network-hashrate-charts/dash-network-hashrate-chart and click on "All") your percentage of the payouts decreases.

That's life...
