I hate to say it, since you already listed "new wires", but this sounds like classic bad wires, or too big spark plug gap. Close the gap to .030 and try again. If not, put the old wires back in.
good luck.

I still think it is a fueling issue. Like I said before mine did the same thing. Check your fuel pressure while you are driving. Base should be @ 44-45psi.
