I've got a 4-phase stepper motor that I'm trying to control, by
sending it the required sequence of 4-bit patterns (1001, 1010, 0110,
0101, repeat), and the motor runs for 2-6 seconds (hundreds of steps)
and then it gets confused and just starts wiggling.

Has anyone else had this problem?  

The motor behaves as it would behave if it had gotten out of
synchronization with the step commands, but I can't imagine why this
would suddenly happen after hundreds of successful steps.

Can anyone give me some advice?

Thanks,
