Fire emitter Blueprint

can someone please help me create an emitter blueprint: that creates a random fire every 5 frames, that each emitter only last 10 seconds each?
I’m sorta new to making things in the engine, but i do understand how the links work.
i got one to create a flame by using create emitter-actor then creating flame at its location, but unless i run it once(using the specific run N times/once) it just spawns a flame every frame, and you can guess how the framerate starts dropping…

if someone could just show me/tell me how to destroy or add a time limit to each created emitter it be grateful.

(although the hundreds of sparks from the spark emitter look cool on a reflection)

Please, can someone help?
