Car starts and throttles well, drives smoothly in the mornings to about half a mile then engine begins to cut power. I changed the sensors the computer is showing and changed cylinder head gasket, plugs and clean fuel injectors, still the same problem. Two months ago I changed the MAF sensor and everything was okay. Now the car is having the same problem. Changed the sensor again and just the same. What could it be?

Hi Olive, it sounds like that fuel pump could be getting hot and weak. You have a pressure gauge? I would definitely take readings when it is cold and hot to see what kind of pressure difference there is, if any. We do not have that model in America so I do not know pressure specs. But I believe that test needs to be done.
