Crankshaft Position Sensor problems of the 2000 Oldsmobile Intrigue

My car stalls while I'm moving! I bought the car from a used lot in Aug 2014, shortly after I received a recall notice. I took the car in to a dealer and the dealer put shells over the keys & supposedly didwhatever else was required in the recall. Shortly after that, I was having a hard time starting the car, I took it back to the lot where I bought it this time. Their mechanic checked it out & determined the crankshaft position sensor needed to be replaced. So they replaced it. Recently my car is having a hard time starting but more importantly, my car will stall while I'm driving! this is scary to be going 25-45 mph and not be able to control my car! this morning I slowed down to turn a corner & it just shut off on me and I could not turn the wheel! caused my to come about 2 feet from hitting a median & almost be rear ended! my kids rode in this vehicle & one or all of us is gonna end up seriously injured or killed! this seems to be a serious issue with these vehicles & it needs to be fixed & quickly! I can't keep praying to have this fixed once a year nor should I have to! this issue needs to be addressed immediately & there should be a recall out regarding this issue!.
