Fuse pump fuse blew

Mikael H

Yesterday I was on my very first longer trip on my busa.
On the way home, the bike died.
After some time, I found out that my fuel pump fuse was bad.
I changed the fuse, and the bike ran perfect again.
Today I looked at all the wiring, and I looked at the pump. Everything looked like new. My bike is a 2000 Hayabusa.
I took it for a drive today also, and the bike runs fine.
Any idea why the fuse blew?
Thank you.
