My IPad Keeps Getting Dropped From Apply tv

My iPad Pro 12.9 frist generation,

• CPU: 2.26 GHz Dual-Core 64-bit Apple A9X
• Display: 12.9-inch with 2734x2048 resolution
• Models: Wi-Fi + Cellular
• Storage: 128 GB
• Model Numbers: A1584 (Wi-Fi)

keeps getting dropped from Apple TV when I airplay something on YouTube. It will start out fine for about five minutes then it will drop. The Wi-Fi is correct I check that already I’m on the same network as the Apple TV. I check connection of my iPad Pro and it’s strong as an able to do other things such as, browse web, watch videos, listen to music on my iPad. If anyone can help me with this problem I would truly appreciate it thank you.
