When ever I am at full throttle my car cuts out at about 4000rpm. At partial throttle it'll go all the way to redline no problem. It does seem like an ignition problem to me since it only does it at full throttle like it is not getting enough fuel. Will the fuel pressure regulator cause this? How about the fuel pump? I am going to change the fuel filter tommorow and see what happens.

I replaced the fuel filter. It was a little better, the filter was not the same size as the large original one and it was dirty a little. I also change fuel hose. The PO had to hoses connected together with a small tube and hose clamps. It might have been restricting the fuel flow becuase since then I haven't had problems with it cutting out.
