Gunk in the carbs or water in the fuel.
Seafoam will possibly fix it.

This may sound silly, but are the plug wires are on tight? and are on the right order? I used to always number mine and spray WD-40 in the inside of the "Boot" in ensure no problems.
I hope you find the issue.

Just An Update As To Whats Going On.......today I Checked The New Plugs That I Had Put In Recently, They Look Great, Tan In Color . I Cleaned The Coils And Sprayed Wiyh Moistier Inhibitor ......got To Looking Around And Decieded To Look Into The Gas Tank, And Noticed What Looked Like Alot Of Settlement And Metalic Like Substance In There....thought This Ain't Right.......so I Proceed To Remove The Tank To Clean It. I Found Two In The Tank Fuel Filters And One Of Them Appeared To Be Starting To Come Apart....needless To Say I Replaced Them. Tommorro I'll Put It All Back Together, And Try It Before The 50 Degree Weather Gets Herre Thats Coming This Weekend. I Don't Want To Do The Seafoam Right Know As I'll Be Putting In Fresh New Gas.....and Hopefully I'll Not Need To Take The Carbs Apart Yet. I'll Keep You Updated As To My Findings As They Develop......

Crazy question but what were the conditions? My buddy with the same sled had this problem with the T.O.R.S. sensor deal. It was rainy and icy and his throttle sensor iced up on him with not enough play. Check it out it might be benneficial

The T.o.r.s. Are Disconnected, So I Think That Can Be Elimiated.....the Conditions Were 30 Degrees Not Snowing, So No Icing Problems..........i Was To Busy To Get Fresh Gas And Try It After Cleaning Today, Maybe Tommorro....
