Hey guys,im new here. I have a 2007 gsxr600. I went to start my bike this morning and I had to hold to down the throttle so it doesn't shut off(~40F outside)Until it warmed up a little. When I started riding I noticed it was sputtering at low end rmps, ten minutes later it was sputtering at the mids also. About 5 mins more into the ride, the bike completely dies and doesn't want to start back up. The engine doesn't turn over, I also can't hear the fuel pump priming or the stva adjusting when I turn the key?! Any ideas of what could be causing this? Any help is appreciated!
