Have a friend look down the driver's side of the engine at the crank pulley while you push in the clutch. If it moves in and out, you have crankwalk. Just pushing in the clutch doesn't put enough load on the engine to make it die otherwise. And the sensor on top of the tranny is the reverse light, it doesn't have anything to do with your problem. Report back to us once you've checked this.
