Probably the Alternator. I do an alternator and battery replacement.

Thanks, I'll try that today and let you know how I get on... (for future reference!)

Yep, it sounds like alternator to me as well. If the alternator is putting out very little juice, higher engine speeds are going to demand more power for spark, etc. If there is not enough to go around, the radio is the first thing to shut down. If the alternator was dead altogether, you would continue losing auxiliary items, including gauges, before finally the engine would die.

Good call both paisan and xwesx.
Both battery and alternator were faulty... I guess it's been a while since I've messed with cars, so I was surprised that the on board computer was able to shut-down non-essential services so quickly and allow the engine to continue to run.
Also, I *thought* the engine was running OK, then after the replacement of both components, it definitely had more zip. I guess 2 1/2 weeks away from the car and I forgot what it sounded like!
Because I'm basically a mug I took it to the dealership to get it fixed, worried that a generic garage would not be able to diagnose anything other than the Alternator and Battery. Yesterday was an expensive day!
 
Quick newbie question though, are Subaru's computer diagnostics generally supported by non Subaru garages?

Most of the codes in OBDII are readable by a generic garage, but there are some items that are only accessable by the Subaru Computer Diag.

Just for reference, the work involved with replacing the alternator and battery is about 30 minutes from start to finish. That, plus around $250 for the two parts. Auto parts stores can usually check those items to determine if they are within spec or not as well.
 
I don't blame you for going to a service department though. If you are not familiar/comfortable with the vehicle's mechanicals, there is peace of mind knowing that the car will work right when you get it back.

02 Outback H6 parking lights no mo by mtbknob

Recently, I noticed that when i used the key fob to lock my car, the parking lights did not blink. Then I was told that I had no tail lights when leaving a parking lot one night. Checked the fuse, it was blown. Tried a new one, blew immediately. Checked accessible wiring in hatch to no avail. Is there a relay on this circuit? anyone have any ideas?
Also, where can one find an easy to use electrical diagram and t.s. guide for the car?
Thanks in advance for answers/suggestions!

You have some kind of short in the lights. I'd look for a cracked bulb to start with. Unfortunately if it's not a bulb it may get tricky to chase down.

Thanks! Found a tail light with the lead contact melted into the ground socket.
I thought I t-shot the problem by disconnecting the the main plugs in the hatch, but apparently, the ground circuit was still intact (doh!) Being at a loss of what to do next, I took your advice and began pulling bulbs... voila!
This all began with a leak in the tail light lens. Everytime I opened the hatch after a good rain, I'd get a dribble out of the interior panel ever since the car was new. The dealer claimed they could not find the source and implied it was my imagination. Finally, after 140K miles, I tore into it and found that when it was assembled, a gasket had been folded over that is just below a little vent in the top of the lens housing. Cleaned it up, and sealed the vent slot with silicone. The car is now sitting in the sun getting the lens housings dry and I'm on my way to the A/P store for some bulbs and fuses Thanks again!
