Why does a 2 stroke engine die at full throttle?
The reason for this is it being a 2-stroke engine. Most 2-strokes are not very efficient and will burn part of the air/fuel mixture as it’s leaving the exhaust port. You’re most likely just seeing the burn. – Pᴀᴜʟsᴛᴇʀ2 ♦ Aug 16 ’18 at 17:01 With trimmer power problems, I always check the spark suppressor screen on the exhaust. Esp with 2-strokes.

Before applying oldturkey’s good suggestions, remove the gas cap and see if engine runs better/longer. If it does this signifies a plugged gas cap vent and is quite common. Dirt and dust can accumulate and eventually plug the vent hole in cap which will restrict fuel flow and can cause engine to quit. Good luck.
