I'd put money on this being the cause. How do you handle the bike with the rear wheel off? Do you just shove it into the trunk or back seat? How do you reinstall the rear wheel?
The rear derailleur has nothing to protect it with the rear wheel off and if you are careless or harsh on your treatment of the bike, that will guarantee repetitive shifting problems.
Remove the front wheel instead of the rear and be sure to position the bike with the
drive side up if you lay it on it's side. I'll bet the problems go away.
