I'm looking at a 90's Legacy wagon, 335,000 miles (!!) but nice engine and trans, but has a habit of intermittantly stalling out 20 minutes after fully warming up.
The car is in decent shape, the trans was recently replaced (although with a FWD trans and not an AWD trans) and the motor is strong; the car appears in good shape, but the new owner said it was stalling after 20 minutes, but can't duplicate the failure.
Any ideas?
