I lost a winning game.
What was my mistake
Sort:
Check down my 25th move, then later on he attacked me check and i could not save

Correct, so you probably weren't winning on move 25 even though you were one move away from mating him!
What could i have played after that, so that i could have won
look , by and by you let the right side go and you want to progress in left.. and by the way you do not have enough material and position there.. and he just kept progressing through the right side.. you let your queen become a weakness point for you.. and he makes the right side another weakness.. so this is a known situation , when 2 weaknesses are found..
I'm not sure if you could have win a game from there. Perhaps 25.0-0 instead of Bc6 could potentially create some counter-chances.
IMO, you should have played differently, for example there was probably no need to spend 3 tempi with your knight just to sacrifice it, and you played some more unnecessary moves with your rook and your queen.
I would consider 13.a4, with later a5, Ke2, etc...
I agree with Dragec, I think your question "how could I have won from 25.Be6 is completely wrong. After that move black will have a strong counterattack and have the advantage. Castling would prevent this and leave you with the advantage. I ran the game through Rybka, and it pretty much said the same thing.
After 24. Qa6+ Kb8 Rybka gives you an advantage of 1,5 even though you are down in material. After castling you could've start to exploit your position on the kingside. Here is the variation rybka gives from the 25th:
It might also be worth noticing that in your game, even though you seem to be in a loosing position after 25.... Qxe4+, you could've saved it to a draw. 27. Ke2 instead of Kd2 would force black to keep mating you with his queen until draw by repetition, otherwise you would mate him...
So ti summarize: Yes, you had a winning position, but this was not on move 25, but on move 24. 25. Bc6 destroyed that winning position.
Oh, and my first annotation in the game above should of course be "Escaping the check-threats from the queen", not the mate-threats.
I did not want to go with that move, as i was one step away from winning the game
Euwe was one step away from checkmate there and this is what has happened:

There were lots more mistakes from you as well. I'll give my thoughts on that later when I have more time.
What about 23.Bc6+ Kb8 24.Qa6?

This thought was your mistake. Obviously, you were not one step away from winning since black could easily start a counterattack that made your mate impossible. You don't earn anything by staring blind at your own possibilities without taking regard of your opponents counter-possibilities.
You should always try to find your opponents best moves and ponder how those could be countered most efficiently. Here, your opponent had really strong counter-moves and you don't seem to have thought about them at all.

Good point fissionfowl, though I think black would not play 25, ... gxh3 but instead 25... Qe6 to allow the queen to travel to c8 and stop the mate (dxe6 would be met by Rxa5).

EDIT: Actually Bxb6 isn't as crushing as I thought as Black can move his Rook and run with his King, still it's an interesting option none-the-less.
2nd EDIT:
I think actually Bxb6 is too much of an unnecessary risk.

24.Bc6+ Kb8 25.Qa6 transposes back into the game.

Oh yeah. Nice Spot!
Not paying attention to your opponent's treats is a big mistake.
Profylaxe, ever heard about it?

Instead of Be3 you should have done Ke2 on move 26
26. Ke2 isn't legal, but maybe you mean Kd2.
26. Kd2 Qxd4+ 27. Ke2 (27. Kf2 Qf4+) Qe4+ 28. Kd2 Rxd5+
Is still winning for black.

Have you noticed that the strong players (mostly with correspondingly higher ratings) have really taken to analysing the moves and not taken for granted the idea that the threat of mate in one is enough to win?
Good point. I think the game's a perfect example of why it's generally a good idea to follow the guideline of looking one move further ahead than what one initially thought sufficient.
