How to solve the 2-hand coordination problem?

[ChampY]

I am doing Waldstein Sonata now. I did slow practising for such a long time. Now, I wanna play faster. But it seems like there is a coordination problem on bar 14 onwards. After playing for a few hours, I can do it. But I cannot do it at the first time when I approch the piano. Considering that in the recital, I definately don't have so much time to warm-up(in fact, in some recital, I don't even have a chance to warm-up at all),I am a bit worried about this problem. Does anyone have any advice?
