Well, this is probably NOT the cause of it, but I had the same thing happen to mine Mid-Ride last weekend. Died in a mudhole, tried to restart, and it was acting like it was not getting fuel. Full choke would get it running momentarily. Tried restarting again, switching the tank to reserve, so on an so forth. Checked the plug, looked good and was dry. Opened the gas cap to see exactly how much fuel was left. tried to restart, and it fired right up. Went to put it back in gear and go and bang... died again. SOMEHOW I got condensation in my fuel VENT line coming out of the gas cap. I popped it off, blew through it and the bike ran great all day after that.
I HAD the vent line extended and run up inside a snorkel, so I didn't check that first. Turns out that the coupling I used had worked itself free and I was left with the factory vent line exposed.
My thought... try starting it with the gas cap off first. I know it's probably not the issue but if it is, you'll save yourself a lot of time and hassle.

I have a '01 600 and it did the same thing, The rubber boot between the carb and intake had a hole in it and was sucking air. Dont know if the 660 has the same rubber boot or not, but worth a try! Good Luck

Welcome to GC jm2778. This sounds like the same exact post I had as my first post. Has the bike been sitting with gas in it? Even a couple of weeks is enough to allow the ethanol in the gas to separate. If the gas isn't treated, the gas separates and the ethanol will collect moisture causing your carburator internals to become gummed up. You will need to remove the carburator and do a thorough cleaning of all the internal channels and jets. Get rid of the gas in the tank, flush it out, clean all the junk and the bottom and put fresh treated gas in it. After that it should run fine. Start treating all your gas with an additive. Lots of opinions on which one to use. I use the Stabil Fuel Marine Grade. Do not use the red stabil fuel additive.
