Stability light keeps coming on

When driving in the snow it came up service stability trax and the stability light came on it then said reducing engine power I pulled over turned the car off then back on drove another 11 miles no problem. Then the next time I went out no snow but still abit icy it came on another 10 or so times each time I would stop turn the car off then back on again the all of a sudden it stopped and never came back on for the rest of the day. I went out in the car two days in a row and it never came on then on the third day it came on twice, then the next two days nothing then the next time I went out in it it done it once again.
