the controller in the enclosure is maybe overheating and either switching into a failsafe mode or a failure mode until it cools down again. sustained data transfers crush those little controllers, so spend more on a better enclosure, actively cool the one you have, or just connect the bare hard drive directly to your PC if that is an option. I've had 2 USB-3 to mSATA enclosures fail permanently after 5 minutes of sustained data transfers.
