Hello fellow Sube Fans! Usually my car works just fine. However, after I have been driving for quite some time, maybe an hour or so, if I park and then try to start the car up again, it is as if everything is dead. There is no turn-over, just a click. Once the car is completely cooled down, it starts right up again with no problems. I have had the wiring and battery checked to rule that out. I recently drove from California to New Mexico. On the trip, I was having trouble idling. The car drove fine but as soon as I stopped at a stop sign or traffic light, the car would just die and I would have to re-start. Since I have been in New Mexico, this issue has not been as prevalent. I am not sure if there is any connection between the two issues. Any ideas? Thank you!
