 I'm blowing fluid out of the top, any reason besides over full that might cause this?  Steering seems okay..

Over fill will do that, also check the return hose for kinks or blockage( the one with hose clamps).

Also make sure your belt is not slipping or oily.

I'm guessing this is when it running?  If you turn the wheel with the engine off, it will spill out.

If all else is well, I agree with overfilling.  As the fluid get hot it expands, and out it comes.
