RC51 won't start

Hi, I'm new to this forum & I just recently sold my R1 and got a 01 RC51. The bike has been running beautiful until today. Today I turned on the bike and it was warming it just fine. While I was putting on my gear, my bike slowly died out and turned off. I realized that I was completely out of gas. I tried a few times to start the bike which it did but once I put it into gear it died out. So I went to get gas and I came back with about a gallon of 91 octane. I filled the gas tank up & realized that it was dripping on the edged of the gas tank hole going into a small little hole which I believe is the overflow valve. I realized that all that gas that went into that hole ended up outside of my left side of the frame. I tried starting my bike but it just stutters when trying to ignite it & wont even start no more. Does anyone have any advice on what my problem is? Someone told me it could be my PCII or fuel pump or fuel fuse
