If an astronaut is left out in space without a space suit, he would die in approximately 2.5 minutes due to lack of oxygen. He would die of the same reason why people die of drowning, hanging, CO poisioning, electric shock, and strangulation.
The lack of breathable oxygen obviously prevents blood from circulating oxygen to different organs of our body, most importantly, the brain. The stranded astronaut will become unconscious in approximately 15 seconds. He would become permanently "brain dead" in about a minute, and within two minutes after that, all of his organs would fail due to lack of oxygen. Medically, this is defined as death by asphyxiation.
If the astronaut is pulled back in within a minute, he might miraculously survive but not without sustaining irreversible damage to his body.
There are many factors come into play when out in space without protection: the lack of pressure, the lack of oxygen, the lack of gravity, the extreme cold, radiation in space.
Our skin is elastic and can stretch. That's how we become fat and get pregnant, and then shrink again. In this process, our skin holds all our insides in instead of allowing them to just burst out. Similarly, when the astronaut loses his suit in space, the skin would keep the pressure in. So no, the astronaut won't burst in space.
However, humans would swell up to twice or even thrice their size when in the vacuum of space without protection. It's caused due to ebullism. At regular pressures, there's smooth conversion of liquid to gas. But at high altitudes like in airplanes, atop mountains, or in outer space, the gases dissolved in our blood will start to collect in the form of bubbles, stretching out the skin and making the astronaut blow up like a balloon. This is actually not as uncommon as we think: astronauts are regularly kept in airlock in the process of rehabilitation to remove excess gas from their blood. So this isn't strong enough to kill either.
Simultaneously, though, the extreme cold in space is going to get to him. If he is recovered within five seconds or so, he can be saved with a few fingers chopped off due to frost bite thanks to flash freezing. There is also extreme radiation which space suits very effectively shield humans from. The skin on the space man would get fried to third degree burns or would now be cancerous or the astronaut would have permanent DNA damage.
If the astronaut decides holding his breath is the way to go, he would end up with ruptured lungs -- and immediate death -- within seconds of exposure.
Due to anoxia to the brain, depending on how resilient the astronaut is, he may or may not recover from unconsciousness and coma if he stays out without protection for anything more than twenty seconds
