Start simple. If it runs fine at the start my be pulling a vacuum on the tank. Let the gas cap a little loose and see if that cures it. I've had several saws that was the cause. Plugged/pinched vent.

How long have you owned the saw? How much use has it had, etc. I agree with Kevin, start simple and try to narrow down the problem by checking one thing at a time, (fresh mix, tank vent, fuel filter, fuel line, impulse line, cranks seals etc. I would also pull the muffler and take a peek at the piston see if any scoring is present. It is a ways down the list, but I have had similar issues with saws that are scored, they will run until they get warm and then they will only run WFO they will die as soon as you let off the throttle. Good luck with it.

Its my first saw and I bought it used about four months ago,as for the fuel mix it high octane gas mixed with the oil 50:1. I only buy a gallon of gas at a time and run what I can and burn the rest later that day on a fire
