The normal operation for a short time is the key. O2 Sensor or circuit
problem. After a restart, the engine runs open loop regardless of temp.

Subject: Loss of Power Problem - Ideas?

Today I finally made what sounds like a good
connection for a Subaru 2.5l Phase II engine, and
somehow my WBX must have heard about it. :-)

Symptoms: While running, loss of power, almost as if
the accelerator cable had suddenly become
disconnected. Engine drops to a very low idle speed,
barely enough to keep going.

Immediately reponds to cycling ignition switch, that
is, if you turn off the engine completely and restart,
it starts back up normally with full power, though it
might repeat the loss of power symptoms within a
minute or less.

Engine has 100K miles since new, plugs,distributor
cap, fuel filter etc all replaced 9 months ago, about
5000 miles.

Where to start?

Thanks

Tom F.
