Intermittent total loss of power at speed - causes?

I have an '09 US model with a little over 11k on it. I'll be anywhere between 45 and 85mph and the motor just loses all power, freewheeling. FI light comes on, then turns off a second later. Then the bike regains power like nothing was wrong. This has happened during acceleration, deceleration/engine braking, and at steady throttle. It has happened in very hot temperatures and mild alike.

I have tried revving the motor hard with the clutch in several times to make this happen on purpose (and maybe clear out potential gunk), but have only been successful once. I have run different tanks of gas through it. At this point I'm thinking some kind of electrical issue, but I'm not sure.

Any ideas on what could be afoot?
Is my best option pulling the seat and running diagnostic modes, or is there something else I'm missing here?

There may possibly be a code set in memory... The FI light will go OFF after being on, if the sensor comes back into range for any reason. The ECU will resume normal operation. However, the event is memorized.

To recover codes set in memory (Diagnostic Mode 2); KEY ON, touch the self-diagnosis terminal rapidly to ground more than 5 times within 2 seconds. The lead must remain grounded (after 5 groundings) for the remainder of the diagnostic session. The code(s) will readout exactly as in Mode 1.

CODE Malfunction

11_______ Main throttle sensor
12_______ Inlet air pressure sensor
13_______ Inlet air temperature sensor
14_______ Water temperature sensor
21_______ Crankshaft sensor
24 & 25___Speed sensor (24 then 25, repeatedly)
31_______Vehicle-down sensor
32_______Subthrottle sensor
33_______Oxygen sensor inactive (Europe)
51_______Ignition Coil #1
52_______Ignition Coil #2
56_______Radiator Fan Relay
62_______Subthrottle valve actuator (sensor in range but not responding)
64_______Air switching valve
67_______Oxygen sensor heater (Europe)
94_______Oxygen sensor out-of-range

Tried several times, no codes. FI light did not light up.

I had the very same problem. The cause was the wiring loom under the seat on the right side rubbing and wearing through to bare wire. Check the frame rail for wear where the loom runs over it and down into the bike frame. If there is any bare wires in the loom one might be grounding out like mine cutting the ignition.

Falling down is your bodies way of saying you just screwed up.

Thanks for the tip. I checked along the loom everywhere i could get to and didn't find any breaks in the outer sheathing. I did find one spot that my shock spring had rubbed the harness some, but not enough to wear through.

Someone had similar problems after pinching his crankshaft position sensor wires when installing crash guards. Others had damaged wires near ignition switch... Does turning steering either way affect it at all? Does everything including gauges and lights go out when it dies?

Well damn, thought your issue sounded just like mine. Maybe keep looking along all the connections for the ignition wiring?
