Welcome to the site !!
Does the MAP switch show any codes/blinking ?? .... It could be a number of things , so you need to eliminate things as you go
It could be the fuel pump , or filter , you did not say anything about maintenance , have you checked the valves ?? , was the bike stored for a few months , and this is the first running of it ?? , if so was the fuel run out before it was put away ?? ,
So lets start with the basics :
Switch blinking ??
Been sitting and first running ??
Been running fine then started doing this without warning ??
Maintenance history ??
Air Filter (clean/dirty/freshly serviced and oiled ???)
Spark Plug , brown color/black color/wet with gas/dry ??
Can you hear the pump run when first kicking it ??
