[s-cars] Sputter, No Boost, Stall, No Start.....New Battery and now No Check Engine Light.....

Wouldn't it be more likely a bad coil being intermittent and then
failing, blowing the fuse?
There is no arcing when it comes to the low voltage side of the coil. 
For a chaffed wire to draw any current, bare wire must be touching the
valve cover.
