Hey Fulks78. You could always try resetting the SMC (System Management Controller) which will revert power back to anything not receiving sufficient power. Just plug your Macbook into the Power Adapter and press and hold the bottom left Shift + Control + Option keys. While holding those keys press the power button once and release all keys.
This is an invisible reset so you won't physically see or hear anything other than the Power Adapter flicker green once. Wait 5-10 seconds after this and try testing the issue out and let me know if it recurs.
Also what Dane N said is a good step to try first!
