Well, here is next suspect...  
How long is the wire connecting the motor with the drive circuit?
According to my experience, motor got mad when I use 2 feet long parallel 
ribbon-like wire to connect it with drive circuit.
I believe it has been caused by external electric noise, or drive voltage drop.

I hope this can be a help.
