The car shuts down when I slow down to under 30 mph. No engine light comes on.This has happened 4 times in the last 5 months. Been in the shop and no-one can figure out why. Any suggestions?

Hi i'm having the same issue with my 2006 chrysler 300 3.5L, I've had it into the shop 4 times due to check engine light on and when i come to stop or get off a exit on the highway it will just die on me. then it starts up again, the last time in came on it was flashing and took it to the dealer they pulled the code which is p0300 which is a multiple misfire however they cant figure out which one is misfiring, they've reset the computer and flashed it due to the TSB on this vehicle and they have cleaned the fuel injectors and i'm still having the same issue. the dealer has had the vehicle for 1.5 weeks and still cant get the problem to duplicate. i'm confused... any advice for me as to whats going on what would cause this, please help me....
