Well great news, it is confirmed the vps isn't going down
root

vps [~]# uptime
04:45:22 up 9 days, 16:14, 1 user, load average: 1.06, 4.71, 8.70
root

vps [~]# hostname
vps.theetop.info
root

vps [~]#
its up 9 days
so its either
1. Your overloading your own vps
2. Some connection issue between you and the vps
your load was 8 1 hour ago so something is using up your resources for sure
