My car is stalling and seems to be heat related. This has been going on since May. It started happening more frequently after I got my battery replaced and even more after I changed from first shift to second shift. My mechanic has replaced a battery cable, replaced a cable where the rubber had worn off, and replaced 2 relays (fuel related). I don't know if this is related, but I also have been having problems with an invertor - it shows a low battery (replaced but no help). This seems to happen whenever I do a lot of stop and starting as in shopping. I can feel it start to choke, the tach flutters, and I start losing power. Finally all the dash lights come on and the engine dies. If I try to restart, it may or may not start. If it does start, it is rough and will die again. My mechanic finally saw it immediately after it died but he said until it totally fails, there isn't much he could do. I am illiterate when it comes to cars. I have a 30 mile drive to work. I have been splitting my drive - drive half way and let the car cool down before continuing my drive. I am desperate to get this fixed because if I am late to work one more time, I will get fired.
