Cruise control stops after braking

I am having an issue with the cruise control on my 2014 Buick LaCrosse. Cruise works fine until I press the brake. The cruise is disengaged which is great but I can not get it to re-engage. I have to turn the car off for 15-20 seconds, then restart. It will work fine until the next brake.

Now here's the kicker. This problem is somewhat intermittent. It might work great for a few hours, then suddenly the problem will show up. It's been doing this for quite some time (year +) but it's becoming more annoying. Any suggestions would be appreciated.

    Has anyone checked the body computer AND the engine controller to see if the brake switch data is correct while the problem is occurring? The brake sensor is a two part device that sends separate information to the BCM and ECM. The data has to match between those two modules or systems like cruise get shut down. There is a chance that the sensor input needs to be retrained and that is done with a professional scan tool.
