      need more detail

      although im not familiar with this issue, however, i think if you try to describe more details of the issue, it may be helpful for others to recognize the error for you.

      - how did it miss? do you mean you can not crank the engine?
      - what did you hear when you try to start the engine at the time it is hot?
      - did you try to open the bonet first, then try to start the engine, then you should hear any noise when you crank the engine.
      - how long do you have to wait until the car is cool down enough to get it start?
      - did it happen if you run the car for more than 5 mins (ex: half an hour or an hour) and then try to start again within 5 mins?

      hope that you will get it fix soon

        Have you pulled up any error codes?

        I say either Air flow meter or Cam sensor.

            have you tried replacing the fuel fliters? also follow fuels lines into the engine. look for fuel lines that could be getting hot when the car is sitting still - you might have a vapour lock problem - a hose may have come off a clamp and be resting against something hot.
