OpenWrt Reboot No Restart of YAMon

About a 3 months ago I installed OpenWrt on my Linksys WRT1900ACS - OpenWrt 18.06.4 r7808-ef686b7292 / LuCI openwrt-18.06. Then last month I added YAMon 3.4.5 / Script: 3.4.7 to monitor the bleeding of bandwidth and the over data charges added to my cable internet bill (overpriced, under-quality). The cable company was recently bought out by another cr@ppy company who recently started data usage. <- I digress. Anyway...

I've noticed in my monitoring of data usage in YAMon it reports a router reboot. I don't see on in my OpenWrt logs. Every once and awhile I am unable to log back into YAMon using: so I puTTY back in and restart YAMon. Which ultimately looses a day of data.

I've checked out this post -> YAMon 3.4.7 doesn't start up after boot and did the suggested "fixes" with only waking up today to do the puTTY restart again.

I am not sure how to permanently fix this problem... please help.
