Hi I have a 96 150 fast strike and went fishing today and after putting boat in water I hit the throttle and it began to plane like normal then it just died like someone pulled my kill switch. so i cranked it again and it just cranked like normal but wouldnt start for a couple of seconds then it just started right up and ran perfect all day.. also my tach has been showing 1000 rpms higher than it really is. Is this a sign of some electrical problem, thanks
