OK, Here's what you need to do. With the key in the OFF position, remove the seat to access the fuse block. There you will find a 6-pin connector with a rubber cap on it. This is the diagnostic plug. Bend a paperclip as a jumper ( or use a wire ) and insert it into the blu/red and the blk pins. Turn the key on and the speedo will indicate the efi code. Once you get the code, contact the dealer to find out where the problem is. I am guessing that the might be a loose connector causing the system to shut down. If you get two codes and the second one is "99" that means there is no start possible.
Shut the key off and remove the jumper wire / clip. That is your diagnostic lesson for the day.
