Before hacking up the wiring any more, check your fuel system. There could be starvation if the fuel pickup or filter is getting clogged, or the fuel pump is dying.

Computer? I have a buddy that installed aftermarket stereo, and one of the speaker magnets was close enough to the computer to scramble it periodically.

Man....
Perhaps a loose connection somewhere...I'm out of ideas, don't know if running a hot wire would fry anything or not.
