Default Subaru shutting off while driving

Pls. help. We have put new sparkplugs & wires on, coil, new fuel pump, filter & relay. The 1998 forester still shuts off while driving. It used to act like it was out ot gas, but now just shuts off. It is very hard to get it restarted. Any insight or advice is appreciated. Thanks. I am trying to stay out of the shop. Thanks.

I wanted to add, the only code it is showing is the knock sensor.Could that cause it? My 2 toyota friends(with 20+yrs. exp in the industry each) say no.

my thoughts would be cam/crank position sensor after trying what you already listed.

I had a car turn off on me on the highway.. I'd pull it over and try to restart it without luck for about 5 minutes.. then later on it would start right up every time... turned out to be the .. oh ****, either the crank or cam position sensor.. I'm pretty sure it was crank though, located near the bottom of the engine. Cleared the issue right up.

Ford power stroke diesel owners some times keep spares in the glove box because it is so common for them. On one buddies we have changed it out twice in an intersection when it has dies and would not start again, both times it was raining heavily.

I happened across this thread and I have a kinda similar problem. I have a 1998 Forester as well, 5-speed manual. Twice in the past week, I've turned the key and nothing happened. All the dashboard lights came on, but no starter. It was rainy both times. Is this a similar problem?

Check the idle air control valve. Our SVX is having the same issue right now. We're currently in the process of replacing the fuel pump, but if that doesn't fix it, the IACV is the next thing we're going after.

According to SOA, the car turning off while driving is "normal".

It may be "normal" to turn off, but why is it doing it & why won't it start back up right away?

Thanks for all the replies. I will let my dh know what you have said.

When I brought this up about my 09 outback (why it stalls itself out when coming up to stop lights), I was told that the vehicle was operating as designed. No explanation given.

If it's throwing a code for the knock sensor then i would start by replacing that. IIRC the orientation of the sensor is important too. Had a buddy with a WRX that ran into similar problems after an engine swap and it turned out to be the knock sensor.

Minnie, what are the symptoms when it won't restart? Does it crank? Do you know if you're getting spark at the plugs? Do you know if you're getting fuel flow to the injectors?

FWIW similar symptoms on my brother's Probe, won't start for a long time (cranks really well) and finally catches and runs just fine. His problem is also the crank position sensor. But before attacking that item check on those three questions I asked above, and also get the CEL code looked at.
