Imagine you're an advanced alien species. To build a spaceship, you need a fusion reactor. You can build one and supply it with helium, but that's the dumbest idea ever. It's so dumb only a human could think of it.
What you will do is, you build a containment shield around the sun, using its own power to catalyze the shield's construction. When the sun is contained, you use its power to build the rest of the ship. You use the sun's power to travel to another star system and you do the same with that star to build another ship.
What I'm saying is, you may wake up one morning, at a chilly temperature, in total darkness, with your sun reading at the observatory's computer "Sun: celestial body absent."
Do you think God will help you? He will be dead along with the rest of us.
The sun is a pretty big thing and it would take a lot of energy to move it. Does the sun put out enough energy to accelerate a mass equivalent to itself and then some at a speed practical for interstellar travel?
I'm not convinced your idea is feasible.
