I've had most of the common mechanical failures, altenator, water leaks, wiper failure, door/hinge problems, roof rust, floor rust, loads of electrical problems. Remember, I'm not a dealer or a mechanic, just an owner like most of you.

Experience Owner of a Discovery. I've had many mishaps with our Disco but I still like this vehicle. Talk to a fellow LR owner instead of a dealership rep. I'm not in this for the money. I'm just an owner who wants to help others.
Question My truck will not restart after running, and shuts of after 5 min idle, and will not restart for about 2 hours.
Answer Hi Robert,
are there any fault codes present? Do you see a check engine light? Could be a number of components that can do this: electronic throttle system or either the crank or camshaft position sensor. Here's what LR repair has to say:
The signal produced by the crankshaft position sensor is critical to engine running. There is no back-up strategy for this sensor and failure of the signal will result in the engine stalling and/or failing to start. If the sensor fails when the engine is running, then the engine will stall, a fault code will be stored and details captured of the battery voltage, engine coolant temperature and intake air temperature at the time of the failure. If the signal fails when the engine is cranking, then the engine will not start and no fault will be stored, as the ECM will not detect that an attempt had been made to start the engine. In both cases the tachometer will also cease to function immediately and the MIL lamp will be permanently illuminated.
It would be better to have a LR mechanic with a Testbook diagnostic device isolate this problem.
