Hi Scott,

I used to have that problem every fall thru winter.  Finally pryed open
my wallet and bought an aftermarket bosch ignition wire set 1 1/2 years
ago.  No problems so far.  I tried all the same stuff, had a miserable
trip thru the mountains for Xmas 2 yrs ago, that's what triggered my
action.  The explanation was an intermittent break in a high tension
wire (probably from the distributor).  Good Luck.
