Description of Problem:

Hello,

I have a problem with my new modpack. When I start new game (new world), several minutes or even hours I can play OK. But suddenly, Minecraft "freezes" with 0FPs and 0 chunks loaded. And, it is the end. When I start the world again, several second it is OK, but then it starts again. Minecraft enver crashed, it only "freezes". I tried to reinstall the modpack, the Tekkit launcher, I updated my Java. The problem is still here.

There is an URL to my modpack: http://www.technicpack.net/api/modpack/honza0297s-modpack

I hope somebody can helps me. I do not know what can be a problem.

And, please, I am not English, so I am sorry for any errors, which I could write.

Thank you for ideas or solvings od the problem.
