Problem with reduced power and stability track
 

I sometimes get the reduced power and stability track issue while driving in my 2009 H3. If I shut it down and wait 5 min it resets and drives fine. It happen late 2012 and did not do it for over a year. Now over past 3 weeks it's done it 3 times. What could be the issue? Now looking back last year my passenger brake light keeps going out and changed the fuse numerous times? Could these be related? I never addressed the fuse issue since it was not a major issue other than one brake light did not work. Finally only one of the 4 main speakers work. Could that be related as we'll? Don't know when that started but it's been a issue for a long time as well. What should I tell the mechanic? Any help would be great. I've seen other replies about encoder motor and brake assembly, are those issues?
