Drive down the road my voltage will drop van will almost stall have to feather gas seems to jump back up on volts and van stays running for few more seconds then does it again. Then eventually it will quit running. Put it in neutral sometimes it will start back up most times it does not. I have replaced coil fuel filter. I was wondering what I have to get next?

If the voltage is dropping then the first thing you need to do is check your charging system.
Here is a link on how to test the alternator.
