Ok this has been a rough trip. Started out with lack of snow. And the 975 wouldn't run right. Got the tps adjusted and fixed an airleak in the intake boots. Cleaned the terminals on the box above the pull rope( not shire what that is) well helped but wouldn't run over6000 rpm. Thought I would take it out today and rode for an hour mostly trail some off trail. Whenwe got back on the trail went about 5 minutes and the digital readout flickered and she was done no spark. Couldn't find any loose wires unplugged kill switch ect. Any body have any ideas with these symptoms.
