i just switched over my fuel system to an electric fuel pump to prepare it for the crossover intakes. ( brute force 650 sra) everything seemed to work just fine until we went riding tonite. i was coming down a hill and it was starting to lose power. when we got to the bottom of the hill it completely died. i let the engine cool down for about 25 minutes while my quad was pulled back home. after we let it cool down it started right back up and ran fine. i think the pump overheated and my solution was to replace the stock fuel lines for some thicker ones and wrap the pump and lines in insulation to keep it from getting as hot.
