I am having the same kind of problem. my car is having trouble sometimes starting after it was driven until it got hot and then turned off. When I try to restart it, the car is totally dead. No clicking sound. Nothing. Its as if the battery is totally dead. I have to try for almost 7 times before it starts. Same problem with my remote starter.

I figured if we can put our heads together, maybe we can come up with some answers to our problem. Email me and maybe we can talk on the phone. If this sounds good to you, I will reply with my phone number or you can send me yours. Thanks, and good luck.
