Stability traction and service brakes soon come on from time to time. Problem?

What is your question?

It's a 2007 LTZ Vortec Max 6.0 and don't think it's my brake booster or master cylinder, because it does not require to mash down on brakes, but my acceleration is lagging a bit. Could it be the throttle sensor, brake sensor? Any help would be greatly appreciated.
