What would happen is the Sun goes off NOW ?

How many times do you have to say.... READ THE MANUAL!!

Is that what causes it

Here are a few things that would happen:

Hell would freeze over (ancient saying for something impossible)
We would all win $10,000,000 in the lotto
We would become immortals
Politicians would become honest
and every other thing that science proves impossible would occur

In other words it just could not happen!

So, what about if just 'my' 1/7,000,000,000th of the Sun went out? Could I
a) win $10,000,000
b) become immortal
c) have an impossible experience (no names, no pack drill)
d) find one honest pol .... oh no, that one is pushing my luck too far!

Can you throw a bucket of water on your portion and see if it works. If it does I want a share of the $10,000,000?

If the sun stopped producing energy you would notice it getting a lot brighter, until the x-rays fried your eyes.

Nearly all the energy that resists a gravitational crush is coming from the core, only a small section of the Sun is fusing matter - maybe a few hundred miles in diameter. Turn this off and you'd have a gravitational crush commence that might take 5 minutes - 3 hours. A lot of heat is still captured between the core and the surface of the Sun. So turn off the core and the shell of the Sun would still radiate energy for around 100,000 years if it didn't gravitationally crush. It takes energy from the core around 100,000 years to get to the surface I recall reading.

Anyway - the Gravitational collapse would release a lot of energy up to the point it goes Nova, then it would blow away the solar system out to beyond Saturn.

Note the Sun's gravitational field doesn't come from its fusion (alone) - the Sun contains around 96% of all mass in our Solar system. Over its 10 billion year life the Sun will radiates about 9% of its total mass as energy. Energy and matter both create a gravitational field - so until the Nova blows past you you shouldn't be able to detect any gravitational change in the Sun's gravitational field.
