MacBook Pro (Retina, 15-inch, Mid 2015) keeps freezing and switching off at random

i bought a used MacBook and every so often it will freeze and shut down, sometimes it will do it continuously and the laptop will be unusable for days or weeks at the time. i've pasted my report in the additional text.

i have already tried all types of resets reinstalled the operating system and resetting NVRAM/PRAM

resetting the  SMC. any other suggestions?
