Probably a long shot but I'm dealing with what sounds like this exact same issue on a 2010 386 with a cm871, did you ever figure out the root cause with this? Driver says it's been doing this for going on 3 years. Used to be very intermittent but now seems to be happening more frequently. Definitely appears to be worse during the summer months and especially on hotter days. Or if anyone else has any insight or suggestions, I'm all ears. Thanks!
