Fusion power using simple hydrogen is the most difficult way to make fusion power and may be impossible in any way that could be used by a space craft. The idea of gathering interstellar hydrogen via a magnetic field is not possible without some way of giving the interstellar hydrogen some level of electrical charge. Various ways of doing this have been proposed but none of them have been tested even in the laboratory. So many new and completely unknown technologies would have to come together for a interstellar fusion ramjet I would have to rate it least likely to ever be used.

Nuclear pulse is a very primitive way to propel a space craft, much of the blast is wasted. A fusion powered space craft wouldn't be much better at total thrust than a ion drive. I suggest you read the article about gaseous fission rockets before you dismiss it.

Why would you need electrical charge for that?

To gather the hydrogen via a magnetic field it has to be charged no way around it. To compress the hydrogen and heat it the hydrogen has to be charged. Regular hydrogen is the most difficult to compress and fuse, that why current designs use deuterium and tritium.

A magnetic sail that gets larger as you move away from the star would allow you get thrust a large distance from your sun, and a magnetic sail could interact with the galactic magnetic field to give some thrust. You could build up a large delta V close to a star and then coast to the next one.
