Runs only with brake

First - What year Spree is this?
Are you sure it is only with the rear brake. On 85-87 Spree, both left
and right switches are wired in series. This means both should do the same thing. Access the brake light switch wiring. Disconnect switches one at a time and see if problem goes away. Does electric starter work normal?
If this is an 85-87 Spree, no ignition switch power is needed to make the engine run. The ign switch supplies power for the brake lights to let the starter relay work and supplies power to the tail light. The rest of the switch is just a kill switch to turn off the eng. It does this by grounding out the CDI unit. It seems it would take a short to ground with the brakes released and some crossed wires at the same time???
Give me more info about year and model. Try what I said about the brake light wiring at the switches and let me know what happens.
