Motor or controller issue. Cart kind of stalls on take off.

I have a 2012 txt with XCT 500 controller and newly installed EMP motor upgrade. First few runs were good after the motor inatall, but today I was riding and came up to a stop sign. I started to accelerate and shortly off the live, the cart kind of stalled and I heard a beep under the seat. The after letting off of the throttle, the cart sped up like normal as I reached a higher speed. The cart continued to stall at each stop until I got home, and the controller would beep. I checked the status light and had a solid green. Any ideas of what may be happening?

I brought the cart home for a charge and will see how it goes after a full charge. Motor temp felt good.

The XCT error flags are self resetting, so they only appear while the error condition exists.

Connect a laptop to the XCT and record a data log while driving cart. If an error occurs, it will be recorded on the log.

Attached is what the first few line entries of a data log generated by my XCT looks like. It has 42 columns of data, plus a few blank columns for spacers between groups of data, so it is fairly wide.

Issue disappeared after charging the batteries. I have a state of charge meter and it showed that I had 2/3 battery left when the stall happened. If it happens again, I will record a session on the computer and see what Alltrax says. I tried to call them today but they are closed until the 2nd. I need to get a digital meter from ScottyB.

Perhaps the low voltage slider is set too high, causing the controller to think it's in a low voltage condition. That can be easily checked/adjusted with a laptop (PC, not apple).
