Yamaha G19 hesitation when starting

[karenms22]

Just bought a Yamaha G19 electric cart a week ago. First time out in the middle of the day, noticed a little slight 1second delay when stepping on gas, attributed it to not knowing the cart. Next day, left at 7am, got up to the golf course, stepped on the gas, got a little buzzing sound, very slight movement. If you kept your foot on the gas for several (10+) seconds, the cart would move perfectly normal. You could ease off the gas and go again with no problem, but if you let completely off of it, you were back at square 1. After an hour of checking wires, we loaded up went home. When we got home, cart ran perfect. Found a loose connection, plugged it in, thought that was the problem. Ran the cart all week after work, no problems at all. Left for the golf course with fully charged cart at 7am the next morning, get there, exact same thing as last weekend. The cold was obviously having an impact on a larger issue. We wiggled a wire, not hard, cart then completely lost power, no more reverse buzzer.

Very frustrating, any ideas. We were thinking solenoid, as the last times we turned the key to the on position we were getting no "click". Would a solenoid going out cause total power failure?? Upon inspection, it has a 2002 controller in it, the batteries are newer (less than a year old), and the solenoid was the only really crusty looking thing on the cart.

I did some more checking, as it turns out the fuse was blown, but not easy to see. Had checked it, but until I put it under light and looked more carefully it was very hard to see. Cart has power again, and seems to run ok, but its been in a garage, don't understand why the cold causes it to stop running.
