My daughter has a 98 Plymouth Breeze, the issue is that it runs and runs good. However, at times while driving the motor will stall or someimes it can be idling, sometimes it'll start right back up or other times it'll take about 5-10min then it'll start. This happens intermittently but usually its a daily occurrence. I have changed the cam shaft sensor, the crank position sensor and checked fuel pressure (49psi while running and 47psi when off). I'm almost leaning towards an alternator issue possibly due to it now whining and can hear audible clicks from the alternator while its running. The reason I'm thinking the alternator is because the alternator also supplies power to the coil pack and plugs to ignite the fuel. Possibly it's loosing that power an causing it to stall? Other than that it throws no codes at all and sometimes it happens when she hits a bump while driving. Its only been doing it on dry days as of now, because its been sitting for over a week in the driveway and it wasn't raining or water on the road when it started this issue. Any help in solving this issue is greatly appreciated. 

Thank you.
