You don't need to iterate in autonomous; assuming you have a sequence of statements (e.g. drive forwards, stop, shoot) they should only execute once each. Look at this example.

Try the following instead:

public void autonomous() {
        robotDrive.setSafetyEnabled(false);
        robotDrive.drive(0.5,0.0);//drive at 50% speed 0% turn
        Timer.delay(5.0);//wait 5 seconds
}

When setSafetyEnabled is true (by default it is), the robot won't drive if the code continues for too long. That's probably causing your robot to stop entirely after ~0.1 seconds.
