I have a new to me auto trany Disco 2 2002 model. If I drive it for say 20 or so minutes and stop at red light the engine will die and not start until it cools off for say 30 minutes and will run fine for around 15 minutes before it is dead again. any help is very much appreciated. Btw I have been doing this in my driveway with the same results. codes are Bank 1 2 oxygen sensor and a Mass air flow sensor.
