Hi broz... last nite while riding home... my raptor suddenly die off..
lights n instruments all still workin.. tried to whack the trottle while on the move n even try start the engine.. but still cant work..

Checked the fuses.. all working fine... push start cant work too...

I've not had the same problem (touch wood) but assuming it's the fuel pump is definitely jumping to conclusions.

Other Possibles - throttle position sensor, power to ecu, fuel blockage, hell even no fuel (are you sure there's juice in the tank !?), water in fuel.

Get some "start ya bastard" or similar spray can of volatiles for hard to start motors. Pull the snorkels off and crank it while spraying into the intakes. If it tries to kick you've got a fuel problem. If it doesn't even think about it you've probably got an electrical problem.

If fuel, then pull the injectors to see if there's anything coming through, then work your way back up the system.

If electrical, pull plug and see if you have any spark. Work your way back from there.

Sounds very much like water in tank,It can see off the pump in a worst case scenario,when you get the bike back make sure the tank drain is clear and working.
