engine shut down while driving
 

I'm driving my 05 T&C down the highway with the cruise set at 70. Suddenly, with no shudder or noise, the engine shut down. I put it in neutral and re started, then had check engine light. My code reader said low barometric pressure. Anybody have a clue on this? Van has 3.3 engine with 67k on it. My warranty is almost up, think maybe I better trade in?

replace the MAP sensor on top of the intake manifold 2 screws hold it on.
