hi rudy, mostlikely your problem is the crank position sensor, when the sensor is faulty and heats up or gets hot, it will cause an open circuit then the computer can no longer monitor the cranks position, therefore in order to prevent damage the computer will shut the engine down and will not allow you it to start until it recieves that signal again, well when the car/sensor cools down , it creates a closed circuit again and can read the signal thus allowing the vehicle to start once again, untill the sensor heats up once again.
