Does it only cut out at WOT in top gear, or any gear? Without knowing more details, it could be electrical, fuel/jetting related etc..... Maybe something simple like a filthy air filter??? Post more info', and i'll try and help a bit more:thumbsup:

I had the same problem with my 03! I had a partially blocked jet. Cleaned her out and was good as new!
