It does seem that something is grounding out the ignition when I let
the brake go. I can not figure out what this could be though. I have
checked the seat safety switch which I thought was the most obvious.
What other switch is in the way of simply running the tractor?

The brake mechanism itself is grounded. Perhaps when you release the brake,
the mechanism contacts a wire with damaged insulation, thus grounding it?
