Program Uninstalling By Iteself

I've installed a piece of software on my computer. The last 3 weeks the software has been susccessfully removed each sunday at 1am. I install it again, the next week it's done. I've looked at event logs, but it just says "system" as the user. I don't see any scheduled tasks that would be doing this, and nothing related to this is showing up in configuration manager logs.

Where should i go from here to identify what is kicking off the uninstall of my software each week?
