If we trace back Haruhi's history, we can tell this much:

Spoiler for vol.1 + 4 + I don't remember:

Spoiler for only for people like Kazu-kun or others who already know the story or doesn't mind being spoiled:

Haruhi first became "aware" of her own existence at that baseball game back when she was in elementary. Since then, she has been trying to lead a more interesting life, to make the world around herself a more interesting one.

But it wasn't until 3 years ago, when she and "John Smith" drew that alien message in her middle school grounds, did Haruhi's "power" began to emerge.

According to Yuki, the symbol that Haruhi (well, "John") drew on the ground that night actually said "I am here" in an alien language. Is this the very first example of Haruhi's "power"? We don't know. What we do know is that John's appearance definitely triggered something in Haruhi on that day, and caused her "power" to go into full swing.

Does Kyon really have some kind of mystic powers? Is he the one who "gave" Haruhi all those powers? Who knows. But one thing's for sure: Kyon is a chosen person for Haruhi. He alone can affect Haruhi in ways that nobody else can. As for the reason... You'll just have to look deeper into their characters.

By the way, it appears that for the DVD release, the episode ordering will be different from the anime. Which means... they're probably putting the episodes back into the right order (Haruhi's order by the timeline) for the DVDs.
