My chainsaw stalls out after running for a short time. It cuts great for a minute or two and then dies. Once it dies it won't restart unless it rests for 10 or 15 minutes.

Before this happened, I just mixed a new batch of 2-stroke gas mixture. Is it possible that the mixture is wrong causing it to stall out when hot? Or is it a coincidence that it happened shortly after the new gas was mixed?
