Hi it would not be the mass flow sensor, it would be more like the cam and/or crank sensor, cam sensor gets a lot of heat on it from the engine this can warp the sensor over time and when it cools down its not in line properly. crank is in the oil all the time and gets hot over time it can overheat. if both of the sensors fail as the read engine speed the engine will cut out. then when you restart the engine light will be on but it will be in limp mode. that means that one of the sensors is reading, then when this fails again the engine will cut out.

You have already spent to much money on a good part. Have the codes read. Or have the car diagnosed. You can get cheap, up to date code readers for $50 to $80 at parts stores.
