97 civic dx when driving along it just stalls, like a switch was thrown and it just dies. If I try to turn it over it will restart for a moment but then dies again, sometimes it'll run for a min sometimes for a couple but never more than 5minutes after it has stalled. When the car is cold it starts and drives without issue. No Code is displayed or shown, the CEL does NOT come on and there are no codes stored. I'm thinking it's the Main Relay but... It's a blistering 37deg F here in Oregon at the moment! Still a bad relay? it's not putting out a code 16 which I would expect either... Anyone have any idea? thanks for the imput!
