So I know these cars are infamous for going through them, but my starter and alternator are brand new, battery is only a year old. Mechanic has checked all three out. Still, every few days my car will just die and not start, usually after a hot start (cold starts are find for some reason). I'll notice the gauge is running anywhere from 9 volts 13 volts during this time. Even at 9 volts shouldn't I at least get a clicking noise?

What is the problem? No gunk on the terminals.....I had a short on a manual fan switch recently, could the short have affected the battery? Mechanic's don't know where to start, claimed that a diode in alternator was causing a drop and getting hot while the car was still cold so I have a brand new alternator. If they just wanted to sell me stuff they would have swore that the battery needs replacing but they say it seems fine. Problem doesn't always reproduce, of course.

Please help/copy all responses to l@laynethrasher.com

Thanks!!!
