2006 mustang chokes on start then dies

i own a 2006 mustang gt, i have recently experienced a problem with my stang.... i've had my car for over a year now and recently (a month ago) i started the engine and less than a minute later it started choking and the rpm goes way below 1000 and the engines dies!!! i took it to the dealer and they said i had a problem with the fuel pump and they reseted the cams!!! got the car back and it was fine for a couple of weeks then, today, i had the exact same problem again!!!

could anyone relate to this problem or know anything about this? i want to know how to talk to the dealer so they don't confuse me with their weird talking!!!!

thanks mustang owners
