I've had that same problem with other cars but it was when the tank was low and it was water in poor quality gas. Generally a stopped up fuel filter will make it hard to start, low power unless you press on the gas over 3/4 the way down and constantly give poor mpg. I don't have any experience with the Subaru in tank fuel filters but if yours is easily accessible changing it may solve the problem.

What brand gas are you using? Is it always the same station? If so, change stations.

I dont know if this applies to Subaru gas tanks, but i know that some gas tanks have a sort of an evaporation tank at the top of the neck where you fill the gas tank. This zone of the tank can get filled with fuel if you try to fill the gas to the very top by forcing in as much fuel as possible. If that happened to you, it would set off the check engine light. Has your check engine light come on?

Also, how many miles are on the car and when was the last time the fuel filter was changed?

If you think something is clogged up, go to the autoparts store and pick up a container of "Seafoam"...I think its what it's called...it's in a red and white circular can...I hear it works very well...you need to add it to a full tank...haven't used it myself though...

/\ This. If you try to fill to much sometimes the overflow will get into the charcoal canister. The evap solenoid might be having a problem too.
