Hm I kind of ran into the same symptoms tonight. It ran great for the past 3 days, and now it just died out and started again after 15 minutes of sitting. It did the same later and took longer to start but I had it towed home anyway because I knew I wouldn't make it without more problems. It turns over gracefully but will not start and if it does it runs for a short few minutes and then just dies out. Do you know the exact issue with the computer and coil? I'm going to check the codes tomorrow morning as I need sleep. Plus I'm stuck doing this myself since I cannot afford a mechanic, nor do I trust other people touching my car.
