Default 2.2L problem: dies out erradically

Like the title says, my 2.2L '96 legacy dies out totally randomly, and there's a tonne of problems that all seem to be related. If I'm writing here it's cause I've already tried the obvious.

Symptoms:
rough idle, goes up passed 1000, then drops to 500, back up, real slow.
When I turn off the car I hear a loud electrical click, about comparable to in volume to a car door shutting.
car may drive 15km and die, or 150 km and die then.
When car dies it seems like its choking, I'm on the throttle but the firing just doesn't seem to be happening.
When the car dies it may smoke and I can sometimes get an AT temp light flashing.

Tests:
IAC cleaned out
Intake cleaned with TB cleaner, from a-z
no CEL code ( i know this is ridiculous, my OBD reads nothing in this case)
AT oil is fine, smells normal, good colour, AT never had an issue.
Exhaust is currently off so it's not the cats.
Thermostat is fine.
Prestone is fine.
car never reads as overheating.
Coolant temp sensor is new.

I suspect something might not be grounded properly, and maybe a coilpack, but would it cause that type of random die-out and all that overheating causing an AT temp light to flash? Is it the AT coolant circuit?

This is my 3rd subaru, but first automatic, never had any problem like this before. I hate automatics.

Well, clean your grounds. I've heard of older cars having something called an ignitor on near the pitch stop mount (dogbone), search on that and see what you can find. You say you've tried the obvious, but what's obvious to me may not seem so to you. Listing what you've done may help others.

Random problems are most likely electrical and not mechanical. Where is this electrical "click" coming from? Could it be a relay dying?

I have no experience w/autos, but the light flashing seems like instrumentation and not an actual overheating.

I did list all the tests, where it says "tests". I agree, the transmission doesn't seem to be overheating at all.

No smoke coming from the exhaust, burns a little rich judging by the occaisional blue flame coming from the exhaust ports, but thats normal. the 02 sensors are curently on the exhaust which is off, manifold all the way back, it needed changing too.

The problem is that the prick I bought the car from did some of his handy man bull**** on it and i gotta figure out what he touched, so I can redo it.
