My Dewalt started doing start/stop when I depress the trigger. Thinking it was the trigger switch that was failing, I proceeded to troubleshoot it. When I removed the battery, I could see one of the contacts was corroded. I cleaned it up and put it back in the drill and voila’ it was not the switch. Three weeks later and it did the same thing. Again cleaning the contact fixed it. Now my question is: Why would the contact get corroded?

The battery must be leaking. If it were me I’d throw the battery away and get a new battery. When you clean the contact, mix some baking soda with water and brush it on, rinse and let dry.
