Sawyer does not die in Lost. In the end of the show, you see Jack in a church with everyone else from the show. Even Sawyer and Kate are there, but they did not die. This is because eventually everyone from the show dies and they are all happy together in a purgatory. So, Sawyer eventually dies and is reinstated with everyone else. After everyone dies, they all move in to heaven or a better place.
Jack, Jin, Sun, Sayid, Locke, Charlie, Juliet, Michael, The man in black, Shannon, Boone, Ana Lucia, Faraday, Libby, Eko, Charlotte, Christian, Ilana, and Jacob die on lost.
