Might sound crazy but check the two wires going to the coil under the front hood..I just had a problem with ours and it had the same symptoms as you describe..It would start but would stall almost immediately after you touched the throttle...After checking some things I was sure it was ignition related and remembered having a problem with those wires being a little loose a couple of years ago..I gave them a wiggle and pushed on them and the bike fired right up and ran great...The last time we rode we got caught in a nasty rain storm and had to ride about an hour to get home so the bike was thoroughly soaked..Then it sat for over a month in the cold garage so it may have started to get a little corrosion going on those two wires which are right up front..
