Welcome to the board. another thing to check is the fuel lines coming out of the tank. Sometimes when you lift the tank and then put it back down the lines can get kinked.

I had the same problem.

Fast accelleration, high rpms or bumpy roads causes the engine to die.

I searched the whole fuel system: nothing...

I finally went to a dynojet center. After 3 hours of riding on the dynojet while removing the tank, airbox, etc. etc. the mechanic started wiggling the wire harnasses underneath the seat.

Then, at one certain moment, the bike died again.

Conclusion: The fuel injection wiring (harnass) had chafed to the frame underneath the seat for several years. So at high rpm's (severe vibrations / g-forces) the bare wire was causing a short circuit which cut out the fuel injectors.

Solution: Repairing the wire and add an extra insulating shield.

No more problems.....  

Advise: Check the electrical wiring for chafing....
