That pause macro i made works fine, you probably copied it wrong way, thing you quoted is not good.
When you copy macro into wide 'Code' bar in macro editor and press Done, it should look like this
Also it may be you trying to pause macro with hotkey that is being used in that macro you're pausing, so it kinda stops and starts itself over and over again.
!STONESKIN!==1
Self.Inventory.Amulet()<>3081
Tibia.SendKey(115) <----- this is F4
U use stoneskin amulet in tibia hotkeys to equip right?
edit:
Here's video, showing that my macro works
