Never had the same problem but it sounds like dodgy connections somewhere. Check out the ECU multi pin connector in the boot. Check the connections under the seletor strip the wires can sometimes get stretched. The only other place, there's a connection block on the the side of the gearbox that can collect dirt. Sorry I can't say I've got the answer, sounds like a job for brianmoore!

sorry, don't know much about switchable autos, although I have one in the shed as the potential recipient of my M54 engine.
Suggest you disconnect the connector to the gearbox and see if that cures the fuse blowing.
If it does then a carefull inspection of the wiring is in order, starting with around the gear selector lever.
