have trouble with my DC maintaining high or proper blade speed. Even is grass is not high it loses blade speed....but when/if i turn either direction the seed picks up immediately.

Have you check belt tension? Check if spindles spin freely. Does engine speed change?

+1 on checking the belt tension. If your motor rpm's aren't dropping while this occurs, it would be a sign of needing to tighten the belt.
