They usualy buck-n-surg when it's fuel pressure and can/DOES happen when the bike is very low on fuel...
Don't remember the FI light coming on when it did that to me (was 2-years ago though) 
Are you sure it's not the oil-light??? I doubt it is but...better safe than sorry!?!?!?
Only other thing comming to mind at the moment is...loose/bad connection somewhere...

No its not the oil light.
Its the FI light. When I turn key off it reset. The bike run
good but when you open full throttle and close it the light
come on and stay.

The ECU doesn't KNOW (and therefore the FI light won't indicate a fault with) the fuel pressure. I'd be checking sensors and all plugs, especially the ones at the base of the tank. I have found that sometimes individual wires come unseated in the plug housing and when you push the plugs together the terminals do not fully seat on each other causing an intermittant fault. I have seen this in the regulator plug at the tail as well. Could be a loose ground somewhere as well. It does not take much to interrupt a ground. A little corrosion or dirt will do it.
