yep full tank, even used the good gas! had added some fuel stabilizer as well.  Coil was my next thought as well as a fuel filter.  Thanks for the ideas!

I would start by checking all the basics:

Fuel - check to see that you have proper fuel pressure

Air - check the pcv valve

Ignition - check to see that there are no visible cracks on the coil in the areas where the plug wires attach

I presume you have a full tank of good gas...
