Sounds like the battery's had it to me - while you have revs up, there is enough charge going straight from the alternator, through the battery and to the ignition system but no charge is being stored in the battery - hence when you lift off, the alternator stops supplying such a large charge to the battery, which in turn (as it has not been storing charge) supplies an inferior charge to the ignition system.
The alternative is the alternator itself could be buggered and is not charging the battery properly - hence when you lift off your ignition system literally drains the battery instantly.
If possibly try borrowing a battery and trying it out on your beamer (or bimmer as you all seem to call them).
Hope this helps
