2005 Nissan Altima stalled out on highway going 52MPH Has history of bucking at steady speeds with or without cruise on and stalling at stops Help from anyone else who has had these problems?

I also have a 2005 Nissan Altima and it has died 4 times since I have had it (45 days). usually does it at lower RPM and speed. I have it at Nissan for the power valve recall right now. and plan to check the Idle Air Control and clean it as soon as I get it back. It is located on the throttle body. I will let you know if it fixes the problem.
