Does anyone have any ideas as to what this problem could be. My 1996 Disco 3.9i V8 Starts and runs very well until I turn the engine off. When the engine is hot (temp gauge showing normal) it will not start. Turn the key and nothing, doesn't even turn the engine but the electric fans kick in when the ignition is on. If i leave it 15 - 20 mins it will start as normal. If i left the engine running it would run all day without fault.
