I have a 1999 Scrambler 500HO 4×4. It starts right up everytime and runs great most of the time. Occasionally while riding it will start bogging and eventually die. I can let it sit for a few minutes and it will start back up and run maybe for the rest of the day or maybe only a few minutes. If I ride for 3 or 4 hours it may do it 2 or 3 times. It acts like it stops getting fuel. I have replaced the fuel filter. Just wondering if anyone else has had similar issues and if so, what they did to fix it?
