Question about Land Rover Discovery
Well, You are describing what is known as a hot chip condition and unfortunately the only common piece between all the effected systems is the ECM. You can most likely pick up a used one at an Auto Salvage a little cheaper than what you have been quoted so far and put it in yourself but $1500 to $4000 is in the correct price range fora new one and most likely that is the only thing that will solve your problems.

Testimonial: "hot chip condition - now I've got something to go on - thanx, CB"
Hi! Thats quite expensive to think that the ECU (engine control unit) has nothing to do with it. The ECU controls the air and fuel mixture so it has nothing to do with failing radio or windows. Its better if he said that its the PCM (powertrain control module), the PCM controls all the circuitry that runs in the car including radio, power windows, locks, ignition, transmission, etc... I would suggest that you change the PCM but before you do that, try swapping the battery and see how it goes. If it turns out fine then its just a battery failure. If still no luck, then its gotta be the PCM. Hope this helps and have a good one!

The only thing that make sense on these problems is you have another bad ignition switch or wiring to it. If noone has actually tested anything yet you need to have this done when the car does not start. I know this can be difficult because it runs most of the time but if your being directed to replace the PCM wtihout a diag then there will be no way to know if its the source of the problem. The worst thing for a mechanic is fixing a car that isnt broken when an intermittant issue is happening. It may be you need a new PCM but I doubt it by all the symptoms you stated. I would be more prone to think you have a wiring or connection issue in the ignition electrical part of the switch or problems in the fuse boxes.
