Need help!!!

I have a 2007- 1200 custom that just did the worst bitch slap a avid rider can ever receive. IT WON'T START!!!

I took it into the dealer for a blown head. After I picked it up I rode for about ten min down the road when at the first stop light the bike started to cut out so I reved it a bit an popped it in neutral. when light went green I dropped Into gear ..... then the engine f&&@ shut off.
got home and parked it for a couple hrs then tried to start it but NOTHING... the engine cranks the pipes pop on for a brief second then it shuts off...

the gas is full. So why is it cutting out. and now refusing to fully crank over??

Double check all your electrical connections,
spark plug wires - both ends ect and anything else the dealer would have to touch to fix (lol) your bike...
after that make sure your getting fuel... hope it helps
