Windstream MPLS random packet loss (every 4-5 hours)

Yesterday at 9:00PM we received a ton of alerts that our MPLS was having packet loss and latency issues go from our main site to our 5 remote sites. It cleared itself up after about 20 minutes. I did my own ping tests and could see about 25% of the pings failing, after it cleared up we were stable at near 100%.

This happened again at 2:30AM, 7:00AM, and now once again at 11:00AM. We have been in contact with Windstream who says everything looks fine. I don't understand what would cause this to happen at intervals like this and then resolve itself. Not sure where to even start looking as this has been relatively rock solid for months and months.
