My car stalled while driving and would not start back

[MSC43]

Luckily I was in my neighborhood and walked back home. I had it towed to the dealership. They said it was the crank shaft sensor. Would this make the car stall after it is running? Once it stalled it would not crank back up. The engine was turning over like it wanted to start.

I thought the engine may of seized because my oil is low when I checked it at the dealership. The car was making a sewing machine noise for about a minute after I first started it. Guessing that was due to the oil level being low. Apparently I need to check the oil more often than I do with this car.

They are replacing that and changing the oil. Hopefully that will fix it. BUT they mentioned they have to replace that and get it running to make sure nothing else is wrong.
This is 2nd time I had to be towed. First was the Clutch Slave Cylinder that went out while driving down the road. Ugh.
