Mine did this when I converted to LEDs. I took the LED bulbs out and put the orgionals back in. They did not flicker. I figure it is my old power converter. The power output may not be stable enough to work properly with LED lighting.

I have no possible explanation if you're running them on batteries, but if you're converting 120v to 12v, then maybe the conversion process from sine wave AC to constant current DC may not be quite up to par, resulting in small cyclic variations in the 12v current that show up as flickering.

Incandescent lights wouldn't exhibit that response, because the filament in an incandescent bulb glows due to its temperature. Small cyclic variations in the current won't change the temperature of the filament enough for you to notice a flicker.

That's just a guess. I'm not an electrical expert, though, so just this once, my 2˘ worth comes at the low, low price of absolutely nothing—with a money-back guarantee.

I think you're correct, it just stopped.

I'm on shore power
