I know this is a common issue and posted regularly, but I've been going through this since I bought the car 8 months ago. The crank position sensor was the first thought, thanks to the advice I received here on this forum. However, I've replaced the crank position sensor more than 4 times and it still dies on me while driving. This last time I waited for the car to restart was 3 1/2 hrs later. I went ahead and sent it to the shop and they can't figure it out also. When it's dead I try to start it, there is no clicking or any sound coming from the engine other than the fan starts on. Not sure what to look into, any advice would be greatly appreciated.
