I have a 2008 Impreza and am having some issues. The car will run fine, though sometimes it is a bit hesitant to start, but will intermittently get a rough tremble to it, like it wants to stall, and then the light that illuminates when you intentionally disable traction control will flash, but it doesn't stall, until today. Today I was driving 80km/h and the vehicle stalled instantly - without a tremble or hesitation, illuminating the battery light, the oil light, the check engine light and the traction control off light. I pulled over and started back up again no problem, drove for about a minute and it stalled out again, same thing, and I started it up again without issue. I made it to my destination, then had another short trip to a friends house without issue. He hooked up his obdii tool and it didn't show any errors in the system. When I was leaving his house I started up my car and a moment after it did the rough tremble and flashed the disable traction control light, perhaps almost stalling, but was fine and I drove all the way home without issue. Any thoughts? I need to resolve this. I see in the impreza section there is an STI that seems to have a similar issue.

I replaced my battery the other day, but had the rough sputtering before then. Sometimes my vehicle seems harder to start then it should be.
I'm going to need a shop to look at it and do whatever needs to be done, but want to have an idea of where to ask them to look.
