If you where to go into space without a space suit, it would take around 13 seconds to die, in that time you would die of suffocation, extreme cold, radiation, blood loss (vacuum would cause all your capillarys to burst), and depending on if there was something betwean you and the sun extreme heat. Or if you are lucky, you could get hit by a micro meteorite and die instantly. I know way to many weird things

I read an interview with Arthur C. Clarke once in which he talked about what would really happen if you were sucked out into space. He said that if you exhaled all of the oxygen from your body (holding your breath would be bad news) before it happened, you could remain conscious for about
two minutes, and death would follow from suffocation in the minutes after losing consciousness. The vacuum would not, he said, instantly burst your veins. I can't remember the reason why, but something prevented the extreme cold and direct sun heat from being a factor. (I think it was something about how your body heat is retained in a vacuum, and how the heat isn't enough to fry you too quickly.) They would affect you, but not until you were dead from the vacuum. It's 2AM and I'm too lazy to look it up, but I'm sure that a Google search for Clarke's name and words like "survive" and "vacuum" will get you some interesting information.

I don't think a micrometeorite would kill instantly. Even if it's traveling really fast, they're less than a millimeter in diameter. It's like getting hit by a piece of dust.
A piece of dust traveling thousands of miles per hour would still go right through you and cause plenty of damage. Instant death I'm not sure of, but I sure wouldn't want it to happen.
