i looked into the crashing, it has nothing to do with Power. both my hubs can provide enough power, i have stress tested it with plugging 3 Moonlanders 2s into 1 Hub, this ran fine without any speed drop. I now have 2 Hubs running 2 moonlanders each.
i wanted to know if anyone has managed to write a Crontab script that restarts the SH file every 1 or 2 hours? if so how did you do it! any help would be great.

You might want to look into
timeout, it should do what you are looking for. Basically run your script in a construct like this:
while true; do timeout 7200 /path/to/your/script-executable; sleep 3; done
