YouTube videos stop randomly?

I have had a problem with YouTube since I bought this macbook pro a while ago. Everything is up to date, my internet connection is good, no other computers or phones in the house have this problem. Basicaly what's happening is the videos will play fine for a couple minutes sometimes up to 10-20 minutes sometimes less than 5, it's just random, and then they will come to a dead stop out of nowhere. To fix it I just refresh the browser and find the spot I left off on but boy oh boy does it ever get annoying! If anyone can help please do!

Thanks,

Michael
