Hello fellow riders i recently purchased a used 2003 suzuki z400 , the quad is clean has a t4 pro circuit exhaust and a K N air filter , i took it out the other day in the snow and about 20 mins of riding the quad just shut off while i was in 3rd gear, i tryed to start it up and it sounded like it wanted to turn over but it wouldnt start i got towed by my buddy back to my house . The next morning i tryed to start it and it turned on with no problems. Does anyone have any idea what the problem could be ? Thanks for your help
