I had the same issue. Pressing down on the brake harder when starting fixed it. I'm guessing dirt buildup on the brake switch. I also found what looks like the starter solenoid under the arm rest. I cleaned that but that did not fix it.

 

I would check this first I had the same issue replaced the brake pressure sensor and voila it started right up.

 

Pull the seats and the upper and lower rear firewalls. The starter solenoid is behind the drivers seat area on the frame.
