Golf cart problem
 

My Yamaha gas golf cart will drive for a while then suddenly die for a matter of seconds, then pick up again, this happens periodically, sometimes can drive one hour and no trouble.
I had the carburetor cleaned last year and problem persisted so had carburetor replaced.

Who diagnosed the cleaning of carburetor and replacement?

I had a similar problem where the engine occasionally would quit. It was diagnosed as a problem with the starter switch. The switch that starts the engine when you press on the gas pedal and kills the engine when you take your foot off was bad. Willie's Golf Carts replaced the switch and we haven't had that problem since. Just something to think about.

I agree check the switch, I just found a problem with 2017 Yamaha BRAKE switch, the lights would go on with lite pressure on the brakes, then if additional pressure was applied, the lights would go out! If the same type of switch (or a similar design) you might have a similar problem.

Willy replaced the carburetor. I will ask him to check the switch.

The accelerator stop switch is sometimes a problem. This is the switch being talked about, under the floor board near the accelerator pedal:

Mine became erratic and I took it apart, cleaned the contacts, and stretched the internal spring a little bit so that there was firmer electrical contact. No problem since.

I would say you have a fuel problem, are you using non ethanol? If not the fuel will deteriorate the fuel line therefore emitting particulate into the fuel going to the carburetor and causing power fluctuations.
You might consider using some fuel additive it can be purchased at any automotive parts store or walmart

Get an electric cart, problem solved.

My vote, too... my Yamaha when newer had two failures of this switch. The most serious was pulling out into traffic gap on Morse from mail station and cart died right in middle of the two lanes. On third switch now for 5 years or so...no further problems.

' using non ethanol? If not the fuel will deteriorate the fuel line therefore emitting particulate into the fuel going to the carburetor and causing power fluctuations '

Try draining the gas tank and putting new gas in it = it sounds like water in the gas tank.

After 7 to 8 trips to the village cart garage in Brownwood they finally replaced my starter and it doesn’t happen anymore They replaced belts before that worked for awhile but came back. They even went as far as replacing my battery and that didn’t help. Just beware

Its the clutch
