1995 E-Z-Go Medalist dying every few blocks then starting up and running for a few more blocks then dying again.

1995 EZGO Medalist 36V.
Batteries 3 years old and still testing good and still shutting off the charger when fully charged. Recently it's dying every few blocks. Then after a short bit, I can start it up again. It runs normally in between dying.

What are the usual culprits that I should check?

To start off, lets take a real time look at how the batteries handle under load, which can reveal a lot about their health and performance. I'd recommend slapping on a multimeter with some alligator clips connected to the main pack terminals and keeping an eye on those batteries while you're out driving, especially up a steep hill.

If things start acting up during your test, stop and feel around for any hot spots- could be wires or components heating up under stress. Heat often points to electrical issues or potential shorts that could be causing your cart to cut out intermittently.

Next, take a good look at all your battery and motor connections. Give them a thorough check for any signs of wear or loose/broken connections. Sometimes, even the smallest break in a wire can cause enough trouble under load to disrupt power flow.

These initial checks are good starting points. They give us a solid foundation to understand what might be going wrong. Keep us in the loop for the next steps

Thank you Michael for the plan. The state of charge meter recently died so I'm going to replace that to keep an eye on the battery pack as you suggest.

I very much appreciate your support in this.

I installed a battery monitor meter and found the pack voltage and voltage fluctuations to be normal.

I noticed the FR switch was very, very stiff. I lubricated points of rotation and oscillated the FR switch many many times. I was thinking that since the dying began after the owner was away for three weeks that maybe the contacts in the FR switch may have become dirty from corrosion. I hoped that flexing the switch back and forth might help to clean those contacts if that indeed were the problem and if indeed it would clean the contacts.

I am happy to report that since I did the above, the cart has been running without dying. Keeping my fingers crossed!

Michael, thank you for all the good tips that I will be keeping in mind to use in future situations like this or if this problem returns here!

I'm glad to hear that your effort with the FR switch has paid off and your cart is running smoothly again. Thanks for the follow up.
