Te449 Cut Out And Backfire

Hello my te449 has a issue where the throttle cuts out and it backfires it only happens once the engine gets hot wondering if anyone has had similar problems i believe it was the fuel pump but im not to sure where to get them from online

Sounds like the fuel pump. Mine would start and run for 10 mins until the pump got warm, then start sputtering and finally quit. It was then hard to start until the pump cooled down for 30 mins or so and then repeat the process. I replaced the pump, in-tank filter and cleaned the injector and all has been fine for years. I used a Quantum pump, but there are many out there (California cycle works, Taco Moto, Best Dual Sport Bikes, etc.)
