    This sounds more like a fuel issue rather than ignition even though you say fuel delivery is good. If you haven't lately changed out the fuel filter it would be a cheap step to take.

    It is possible for ignition to do this. Old plugs and wires can even make it happen but I'd start with the above.

    this recently happen to me but im not sure if it may work for you but there is a fuel filter inside of the fuel pump and if this gets clogged with any type of gunk or anything you may have what i had at like 50mph my engine would start to act up the same way because it was not getting the proper amount of fuel
    thats just my recent experence but im not sue if it will match with your problem :)

    Fuel pressure doesn't mean much. It is fuel volume that counts.
