Can anybody help please?

Having read some of the link I would suggest looking again at the basics. Battery terminals & Negative leads to chassis & engine are the most obvious. If EVERYTHING is cutting out including stereo then unlikely to be an engine problem. Ignition switch is a possibility but I'm not sure of the setup on the E46. How often is this happening. The more frequent it occurs the easier to trace.

happened once about 3 weeks ago, but it was so quick, wondered if it was just me, then yesterday did it once, and today on way to gym done it twice in space of 5 minutes.Hmm nightmare!
I'd try running some additional temporary earths to see if the problem goes away. Failing that I've thrown good money after bad trying to fix electrical problems, taken it to an auto electrician and the problem was fixed for a fraction of what I spent replacing bits!
Good luck

I had an E46 M3 cab until earlier this year which was doing EXACTLY the same thing!
Try wrapping relatively thick tin foil around the battery terminals and doing the connections up then.
The terminals on the batteries used in M3's are (apparently) notorious for wearing down and losing connection. Also, as the batteries are in the boot almost directly above the rear wheels and the suspension is so harsh on the car, it moves around a lot more when going over about 30mph and causes temporary loss of electrickery.

Hi Peeps....
so i think ive solved it, after jumping it of the wife's corsa.....(nearly killing it) i got it started.
Checked over the battery connections but while the engine was running before i touched them i could hear i kinda arcing, found that they were both pretty loose. im guessing that the battery just wasn't getting charged?? but i took it for a spin in the wet.... so not so white at moment, and she was fine. was out tonight for about hour and half with no issues what so ever.
i do want to take the connectors off and do the tinfoil idea mentioned before, but i dont have bloody codes for radio/nav unit.
Thanks for all your help and advice

If you are careful you could use jump leads from the corsa to provide 12v whilst you add the foil to the terminalsso i think ive solved it, after jumping it of the wife's corsa.....(nearly killing it) i got it started.

To overcome the 'careful' bit above connect the jump leads in the engine bay using the master 12volt terminal. That way you can work away in the boot without fear of disturbing your temporary supply.Steve
