1990 Legacy wagon starts up, drives for about 30 minutes in rain or wet snow, then starts misfiring and dies. Will start right back up, but acts as if not running on all cylinders. Tach all over the place but no power. Can sit for awhile, then nurse it a couple more miles and it dies all over again.
Replaced spark plug wires, fuel pump.
Is there a crankshaft position sensor that could be getting wet?
