E46 M3 will stall when shift to neutral, and now crank won't start

Hi there!

My E46 m3 early in this week will just randomly stall when I shift to neutral when I come to a stop in the traffic. Now the issue got worse today. The car just stall at the traffic light and die on me where I couldn't turn on the engine. The car will still crank but just can't start. I am thinking it might be the issue of Crankshaft position sensor?

And there's no check engine light or other. The only code i'm having right now are the P0172(System too rich bank 1) and P0442(small evap leak)

Any thought would be much appreciated!
