after driving the car about 50 minutes the air conditiong slows down and stops blowing, sometimes the louvers feel cold but no cold air comes out..seems like you can hear the fan blowing but nothing coming out...if I put the car in neutral and turn off the engine then restart everything comes back to normal..?? and suggestions?

It sounds like you have a blend door issue. This can sometimes be related to a vacuum leak or heater case failure. Also I have seen AC pushbutton control modules act in a similar manner when failing.
