Really need someone who could give me an idea of what it might ve

Check engine light on?

Any mods?

How old are the spark plugs? Air filter? PCV valve?

it comes on and blinks for about a minute after it happens no mods bone stock and I just bought it so idk about that

Get a code scanner, or take it by an auto parts store and ask them to scan the check engine codes. Post any codes here and we can work from there.

 

At the very least you should do a basic tune-up. NGK Spark plugs, Subaru OE PCV valve, new air filter, new fuel filter if its replaceable. Check all of the vacuum and PCV hoses and replace any that are loose or cracked.
