I have an 2004 m2 with a cat3126,I recently had it lay down on me an I need an opinion on where to start diagnosing this problem.it shut down like I cut off the switch,spins great but no run.i noticed the dummy lights come on with the switch an flicker an fade away to off.cut the switch off an back on an they do that every time.it seems the computer is losing power,I have checked all the batt grounds an power connections at the bat an at the starter.i let it sit for a few hours an tryed it an it fired up an ran great for 7-8 min,then cut off again,what you think?computer? Connection?
