07 Yamaha Drive - intermittant power loss

[richardnfuller@gmail.com]

Upon initial power up, this cart lunges forward and stops. Reset of tow switch would re-engage(click) motor and cart would start and lunge again. After about four times, cart would run fine. Bypassed tow switch and after thinking problem solved, next morning cart still acted the same. After multiple starts and stops, it engages and runs fine. Cart is in great shape, no loose wires, new batteries that charge up fine. Where might I start to look? or do I need to take it to the cart shop?
