I have a '05 Ducati SS800 and I am having a hard time keeping it running right now. I was riding and all of a sudden it started surging and misfiring, I couldn't get it up over 30 mph! I made it home and now it starts for a few minutes then dies. It sputters and sounds like crap then cuts off. what could this be? I checked the spark plugs and they look good, fuel is good, any guesses??

You should try some basic checks first.
Try new spark plugs, check compression, air filter.
Have you made sure the whole fuel system is clean?
Some gas tanks develop rust quickly and bits of it
can plug the gas tap, fuel pump and lines.
You should also check for any intake or vacuum hose leaks.
The gas cap vents can be a problem too.
You may need to have the fuel injection checked
by a Ducati dealer if all else fails.
I Hope this helps =)

Sounds like fuel is "not good."
Check the whole system. I don't know if it has a fuel pump, but include that, if it does. Check everything -- pull the hose off the carb and make sure you have LOTS of gas flowing. If it increases when you open the gas cap, the cap is plugged. If that doesn't fix it, work your way along the fuel line, disconnecting at each juncture -- fuel filter, fuel pump, petcock, and the other side.
If all that flows good, you'll probably find the problem in the float bowl.

I agree, contact Ducati. However, I will say this, it is probably the fuel. I would suggest siphoning out the fuel and replacing it with fresh Fuel. However first, I would have the Carburetor clean, clear and clean the Jets, and then swap out the oil Fuel for Fresh Fuel. It sounds like the Fuel supply has been contaminated with either water or worse case ... sludge. The only way to find out is to get the old fuel out. No Sludge...oh happy day. Just replace it with Fresh Fuel. If that doesn't work, take it in to a dealer to have them clean the Carburetor for you.

I had a similar problem with my 620SS, i found a nick in the wiring that had been caused by the Ducati dealer when servicing. This made the engine run on one cylinder from time to time and sometimes i couldn't get it started, then it would start to run then die etc..
Just a thought.

My husband and I both ride Ducatis (996). It sounds like you may have picked up some bad fuel along the way. Drain it out and start fresh with some good quality premium gas (like Shell).

If you can get the engine RPMs up fairly high with no load on the engine, then the ignition is fine.
If you can't get the engine RPMs up under load, then you have fuel supply issues, or plugged air filter.
I'm leaning toward fuel supply. Maybe the tank air vent is stuck and not letting air into the tank as the fuel level drops.
Maybe fuel filter?

I had two late model SS with temp sensors on the front cylinder go bad. It's a possibility. Best to invest in a factory manual if you're capable or take it to the dealer or Duc specialty shop. If you choose the latter, they would appreciate it if you don't start pulling crap apart before they get a chance to look at it. Diagnosing what's wrong with your bike on top of what you did to it will only cost you more $$$!!!
