There are two versions of this series one with just the iGPU (Intel chip graphics engine) and the other with a AMD GPU chip. Do you know which you have? Here's a listing of this series:

If you take the bottom cover off you can see the difference in the heat sink as it will either only have one chip pad or two. Follow this guide to get it off MacBook Pro 15" Retina Display Mid 2015 Lower Case Replacement

@suck24877 Can you take the bottom cover off and take a couple of good photo's so we can see, posting them here.

If you got a crash report that would be helpful when diagnostics doesn't pop an error. From the sounds of it it sounds like the GPU maybe failing or just overheating. Are you up to cleaning the logic board and re-pasting the thermal paste on both the CPU and GPU if present.
