While motoring to Spencer's Spit on Lopez Island, the engine began to run increasingley rough, as though running out of fuel.  The fuel gauge showed nearly a full tank, and I tried a couple of hings to resolve the engine problem, with virtually no pwer coming from the engine and wind and current bringing me to the shore, (too close to anchor) I began to ready the maim sail to raise.  While using the topping lift to raise the boom, the line parted, acasuing the boom to strike me on the back of the head and out cold.  By the same time I came around and ragained my senses, the boat was on the beach.
