98 Grand Prix 3800 sfi engine shuts off

I read in a number of messages that a malfunctioning crankshaft position sensor is a strong suspect in intermittent shut downs of the engine. It usually start right up again. Does this engine also have a camshaft position sensor that has to be consifered?

Replaced CPS, still have same problem. This is my daughter's car and she is experiencing MORE symptoms: Most often, just before the engine shuts off, the radio volume decreases markedly, also the TRAC indicator light goes nuts. I experienced this once but had written it off as a coincidence. It seems to me that there could be a drop in control voltage or current which leads to an engine shutdown. Anybody have any thoughts or like experience?
