Shutter Motor Kit Installation

I'm having lots of trouble with my shutter. When it works it's awesome. But in the past year and a half it's only worked properly for about 7 months of that. I recently had it upgraded/fixed... installed and all was again good. I had 2 clear nights since then (rare in Michigan in the winter). and it worked fine. So the other day (3rd time I've used the new replacement setup). I'm demoing the dome setup to a friend on nightskiesnetwork. I had about a dozen people pop in and I had issued with the shutter not working again. (wasn't good for sales). I went out the next day and discovered the shutter data (where does it store its settings?) is corrected again (as was the case before I had it replaced). The driver data fields. (version, volts, low, steps etc) are all missing or wrong or (rarely) volts is correct). I hate to send it all back in again. What board or part would cause this? Each time I connect I get something different. When I try to open the shutter I get a very VERY slow ticking of the motor that SLOWLY increases in speed. When I release the rocker button the ticking very VERY SLOWLY slows down before stopping. (as if in super slo motion).
