EZGO works one day, and doesn't the next

[XCOP1152]

We have an older EZGO txt. I think it's a 2000 model. When it runs it runs great, but lately it has started intermittently not working.

Yesterday morning I turned the key and it worked great, drove around the yard, and parked it. Yesterday afternoon I turned the key, hit the pedal, and nothing at all.

This happens everyday. It will work one day, and not the next, and then it starts working again for seemingly no reason. Nothing seems to be happening to cause it to work or not work.

We have checked the key switch, and the accelerator box under the floor panel. The batteries are fine. All connections have been cleaned and tightened.

This is frustrating.

Can anyone point me in the right direction or give me some advice? Thank you.
