Unfortunately, my car died on me last night - coming home from an evening night out

So, called the AA and out he came. Checked the injections with a little gadget which flashes which I don't know what that proves, and straight away...he said that the Crank shaft sensor is most likely the problem. However, i did noticed in the past couple of weeks that starting the car wasn't so sharp as it use to be as it took a few turns before the engine came to life - as before, it used to start pretty much straight away after a push of the button.
Could there be any other possibilities that may result this on going problem or is the Crank shaft sensor is most likey culprit!
Any feedback and suggestions will be much appreicated
Thank you
