Seems like your battery is failing and needs to be replaced. What is the battery condition as reported by macOS? Is it "Service Recommended"? If so, then you need to get the battery replaced. Have Apple or an Apple Authorized Service Provider examine the laptop to provide you with a repair estimate.
