Will gravitational force increase or decrease in power in a high amount of energy?

I think what you are asking is if energy gravitates. In General Relativity, yes it does, and large energy densities gravitate more.

Gravitational force in high energy
,I am asking whether gravity becomes stronger or weaker in higher energy.

As cosmik said, in GR both mass and energy curve spacetime, so yes, the more energy you have will result in "stronger gravity".
[tex]{R_{\mu v}\frac{1}{2}g_{\mu v}R = 8 \pi G T_{\mu v}}[/tex] This is how we describe a gravitational field in GR. The left hand side of the equation basically describes the curvature of space, while the T on the right hand side is the matter+energy you're dealing with it. This equation is the Maxwell equations of GR since it describes the generation of fields in GR.

I think you Neutrino might be alluding to some grand unified theory which puts the strength of the gravitational interaction equal to the strength of electromagnetic and strong, only at high enough energies.

Let's stop trying to guess what he means and let him explain what he means.

okay, how about I rephrase it in another way. How does energy affect gravity?

General Relativity is the description of how energy affects gravity. Specifically, Einstein Field Equation relates stressenergy tensor to the spacetime curvature, the later being responsible for the effect of gravity. Does that help? If not, you'll need to be more specific.
