Astronomers do not believe the sun will end its life cycle as a black hole because it is not massive enough. The sun is a medium-sized star, and only stars significantly more massive than the sun can end their lives as black holes after undergoing supernova explosions. The sun will eventually become a red giant and then shed its outer layers, leaving behind a white dwarf, rather than collapsing into a black hole.
