Could be vapor lock in the fuel system. Next time it does this, stop and try removing the fuel filler cap... Hope this helps...;-)

You could have any of these problems:
1) vacuum leak- broken air hose or disconnected air hose.
2) water in the gasoline- add a water remover to you gas tank.
3) bad or disconnected spark plug wire(s).
If this were my Forester, I'd take it to a mechanic who has a electronic engine tester..

It sounds like your vehicle needs a major tune-up. Try putting in some fuel injector cleaner gas additive and a new air intake filter.

Coil pack should in the front top of motor, with engine running remove one spark plug wire at a time from coil pack ( careful not to get shock ) they should all have spark, if one don't replace coil pack.
