Narrative:

Aircraft was parked on the ramp. The aircraft was loaded and engine covers secured in aircraft. Aircraft engines were started and preflight check completed. Props and mixture full forward and gear three green down and locked. On taxi everything was normal and proceeded to takeoff roll. Prior to redline the nose suddenly dropped and aircraft came to a stop on the runway. It appeared that the nose gear retracted and dropped aircraft to runway. The only thing I can figure is that the front passenger was large and may have bumped the gear lever in some manner. It is directly in front of the passenger.
