I have a 2005 electric EZGO TXT 36 volt golf cart. After riding a little bit, still with almost a full charge, the cart will just stop running. I put it in forward and reverse and pressed the pedal and nothing. After letting it sit for a few minutes, I pushed the pedal down all the way and it slowly, very slowly came up to speed. Now it will go but it hesitates and kind of shutters and takes off really slow. Any suggestions greatly appreciated.
