Way back when, I had several instances where the bike just stopped dead and wouldn't start again. Turned out to the Throttle Position Sensor was way out of alignment. Well, so the dealer told me. Certainly, once adjusted it never happened again.
On an old CBX550 (cor, remember those?) a similar problem was tracked to the coils breaking down at high temperatures, but modern bikes have way better build quality these days and the Fazer has two coils but something else may be breaking the connection as it heats up as has been suggested above. There are a number of white connectors all over the bike and they might be corroded. Start with the big white one under the tank on the near side. It's known to a be a problem... I was stranded for hours.
