I agree with wiring issues...had a similar problem with mine turned out that two of my grounds were loose and the wire going to my alternator had deteriated after I tighten the bolts and replaced the clip for the alternator I haven't seen any issues. Hopefully yours is as simple as that bad plug wire.

 

Craby gets a gold star. When I took out the plug the insulator crumbled into pieces. Thanks everyone, runs like a charm

 

WOOT, to think all that time and frustration from a spark plug insulator DOH!

 

kool deal, good to hear you got it. enjoy
