I don't wish to terrify you but...

I had a very similar problem appear with my '89 535i. My car started to 'miss' very briefly, which was not much of a problem while driving, but would result in a stall at idle. My dealership had the car for a week diagnosing the problem and at long last determined that the Motronic aka. 'Moronic' contol unit was faulty. It was huge $$$$.

Luckily in my case the car was still covered under a warranty. Whew!

Sounds to me like your problem is in the ignition system...just make sure everything else is in working order before replacing the Motronic unit!

Good Luck
