It mostly happens in the retail lot. especially if I am asking the sim to ring up a customer. It will pause for several seconds. pausing and unpausing sometimes helps, but only randomly. it occasionally do this when standing in front of a bassinet for a baby as well. but it mostly in the store. Sometimes I can't get it the sim to make any money because all the sims needing to make a purchase have walked out , before the sim is ready to respond to the first customer. I own the Get to Work and Cats and Dogs expansion packs, as well as the great outdoors, and kitchen cool stuff. It is all for the pc. It is fully updated. But, I will try the game repair. I don't have any mods or cc. I will check out the guide as well.
I recognize this as well, I fear my computer may be underpowered for the Sims 4. You could post your computer specifications, or better, make a dxdiag report of it, for more information to be visible. I can't promise I will be able to understand all of it, but there are other players here that are good at hardware and I'm sure they'll try to help.

Also, could you tell what fps you get. When in game press keys Ctrl+Shift+C and type in: fps on , the hit enter. The number is usually in the upper right corner. Play for 10 min or so, and keep and eye on it and write back what different numbers you get. I'm not sure it is actually related to your problem, but it could be interesting to know anyway. To get the number to disappear you can either just exit the game, or bring up the cheat console again and type: fps off (and enter).
