You describe the same problem I had.  The speed sensor for the ABS reads 
gaps or teeth around the hub of each wheel.  If the ABS *thinks* it 
is getting an improper reading, it shuts the ABS down.  Previous 
posts (check the archives) recently (within 3 weeks?) have talked 
about proper clearances between the sensor and the teeth.  I just 
pushed one of mine in until it hit the teeth, and then backed it 
out slightly - works fine now. The sensor has a bolt  which keeps it 
from backing out, but is a press fit otherwise.
