I have a 2001 Club Car IQ 48V. It has been lifted 6 inches, big wheels and tires etc. I use it in a gated community no major off roading. I have a problem that keeps happening and it is getting frustrating. All the batteries are new and fully charged, all cables are good and tight all other connections and terminals I can find are good and tight. There problem it I can take off and be driving and it it will be going just fine and it will start beeping and stop. I can let off the gas pedal and hit it again and it will take off. It might go 100 yards and do it again or it might go a few miles. It is intermitten as to when it will happen or how far it will go before it happens again. Any suggestions?
