How do i make the charactor invincible for 2 seconds (basicly taking away the collision)?

So i am making a Endless Runner type game. I assume you have watched these tutorials on how to get started with one: A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums. When the player dies i have a UI pop-up asking the player to save the character and keep playing (havn’t added the gem part yet)

The progress bar represents how much time the player has before that screen is taken away and replaced with the stats. Anyhow, when the button is clicked i want to turn of the character mesh’s collision so it doesn’t keep hitting obstacles but only for 2 seconds. Here is what i have so far:

For some reason this doesn’t work and the character keeps hitting the same obstacle again and again when you press the “Save Me” button making you die over and over again as soon as it is clicked. Any help would be GREATLY APPRECIATED!!
Thank you in advanced.

I’m afraid i got lost. Could you use some pictures or some details please. I’m kind of new to the collision department and i don’t know everything about blueprints. Thank you
