1998 Dodge Intrepid No Spark

I was driving down the road at 35 mph and as I was driving my car just completely lost all power and stalled. So I let it sit for about 15 minutes and then tried starting the car and nothing. So I got the car towed home and started messing
around with the car. I went through all the fuses all were good. I also checked the fuel pump to make sure it was working it was. Just to be 100% sure I took the air cleaner off the throttle body and sprayed starting fluid in and tried starting the car nothing. Then I took apart and replaced the cam shaft sensor still nothing. This make and model dodge intrepid has coils over each spark plug, so I pulled the first coil off the plug and checked for spark and got nothing so I also checked coils 2 and 3 no spark. So my question is what would cause the car to get no power to the coils? Any input would be greatly appreciated.
