how much do all the crankshaft position sensor cost?

What is your question?

My car has been shutting off lately while I am driving and my father and I figured that it was the crankshaft position sensor. This has happened plenty of times and sometimes it wouldnt start back for a while. We really need to know how much these sensors cost.
