I've owned my wagon for almost 2 months now, and it's been troublefree since day one. But I guess something was bound to happen...

Went to start her up today (with the proper amount of glow plug time of course), and it turned over and sputtered a bit and then stopped. Did the glow plugs again, and it started fine. Okay.

Now, I'm driving towards my first stop, and as I approach the intersection it dies again. Start it up again, and this time it's running a little rough (similar to very low idle). Runs fine for a while, come to another stop sign and it dies again. Now I'm worried.

While this is happening, I happen to notice that my fuel needle is in reserve territory, but the light is not on. (At this point, I haven't put 2 + 2 together yet.) As I go on my way, the fuel light comes on, and now I notice it's running pretty hard. (Now the light goes on in my head!)

So I find the closest station (paid $1.53, btw, ouch) and fill up. And to my amazement, it's running fine now. How is this possible? The car came with brand new fuel filters, has been running great up to this point, and then I run a "little" low on fuel and it feels like it wants to fall apart...

Is the solution not to let it get below a 1/4 of a tank? Do I have an injection problem? If so, wouldn't I have noticed sooner?
