Car does not stall completely and this usely happens while driving down the road. Then it will be OK for awhile and then all of a sudden it does it again.

This may not fix it but re-check the plug wires and plugs.

You may have a ECM fault and may have to be scope tested.

Any CEL and new codes?

It seems to me to be more related to something electric than mechanical.
