Driving 70mph...suddenly car seems like it is not getting fuel. Every time I touch the gas pedal it slows down more. Coasted to stop, engine died. Will restart but, only for a seconds. Throwing MAP sensor code.

Would stall for no reason, could be a day a few hours before it stalls. Changed the fuel filter and recieved a complete tune up, the car drives better but still stalls a takes a while to start up.

I think my engine is a 3.8 liter V6... Anyway there was a mystery stall problem while drinving through the mountains of Penn on the way to NYC a chevy dealer ran a diagnosis could not find anything but replaced the fuel sensor... This worked for about 100 miles when it stalled again and a few times more before it made it to NYC... No codes thrown... The car finally died on 8th avenue and 30th street in Manhattan.. It was towed to a garage the fuel pump and fuel filter were replaced.. Now the car runs fine...
