My 01 gsxr randomly dies while riding. Everytime it does you cant hear the fuel pump running. The weird thing is I can let in run in my garage for a half hour and it wont die so I can check it. Only when im out riding is when it gives me problems. Im assuming it is the pump but want to check it to be sure. Is it possible to be something else or am i waisting my time and should just get a new pump.
