I've changed my crank shaft position sensor three times and the code still saying I need one. Can someone please help

My 03 Cadillac cts have been driving rough and engine stalling while I am driving. I had the transmission replaced in May. (Used) then days later, engine light comes on. A couple weeks later, my car starts running rough and engine off when driving. I replaced the fuel filter. Still same problem. I had the sensors cleaned. Still same problem . Now it sounds like all symptoms is same. Maybe crankshaft position is bad
-
Yes. From what you described, sound like you have a bad Crankshaft Position Sensor.
