Help with random reboots.

Not sure if anyone can help, but whenever I install macOS through clover, it abruptly restarts.

1. Boot to clover -> install from USB restarts @ 2 minutes to go
2. Boot to clover -> run from hard drive, Apple logo with progress bar shows for 3 minutes, screen goes grey and have cursor control for ~10 seconds, then it abruptly restarts
3. Boot to clover -> run from hard drive, "This machine restarted due to a problem", apple logo shows for ~3 minutes "15 minutes remaining" and it restarts again.

I've used linusYang's repo, kk1987's repo i've used rehabMan's laptop tutorial, the vanilla guide, and it all shows the same problem - the restart when installing (I think this is expected behaviour), then restarts during boot from the actual macOS partition.

My hardware is a lenovo t480s:

• Intel Core I5 8350u, 8th gen, up to 3.6 Ghz
• 16 Gb memory
• 256 Gb SSD
• 14.1" Full HD 1920x1080p
• Intel UHD Graphics 620
• Webcam
• Wireless, bluetooth
• USB 3.0, USB type-c, HDMI

Thanks.
