I have the exact same problem on my 89 BII. Sure would be interested in the fix when you figure it out.

Well I replaced the Ignition coil, and it did it for about an hour or so of driving, then it all stoped. A week later its still working fine... Will keep posted. It may have been a bad ground connection at the coil.
