My 98' Outback Legacy won't start (intermittently) when it's been running for a while or if it's is hot outside (above 75 deg). The car won't even crank--just a click sound. Usually if I wait about 20 mins it will start just fine. All electrical devices in the car work-- stereo, headlights, horn, radio, etc. It will ALWAYS start if I have someone jump the car.
So...I replaced the battery and it still won't start on occasion. Any ideas?
