Are you using mods in your game ?
i'm not using any mods and it is a brand new game installation
Is your progress actually being saved or do you have the feeling you loose what you played ?
progress is saved but playing is virtually impossible when the game is being like this. I'm wondering if the game is clashing with other computer processes?
I doubt that.
Could you try this: http://sims4.crinrict.com/en/2014/09/resetting-the-game-to-factory-settings-without-reinstalling/
Start a new game for testing purposes before putting anything back and see if you have the same issue.
