You are asking about Entropy effect. There is a theory were in one specific day, all suns will cease to "burn".
"...The sun will take a total of around 5,000,000,000 years to release the nuclear energy in its hydrogen that is fusing to form helium. Some people see this a cause for despair even from the vantage point of our 12,000 year old civilization. Others are not perturbed..."
Entropy is the keywprd associated with your question,but unfortunatelly its associated to the technique to measure solar flares.
You can go foward into Google and find more about it.
Of course, its only a supposition, once Humankind do nto have enough knowledge about Sun, Temperature and Complete composition. Only theories. Las 5 years, they learn a lot and in next 10years, a lot of things will appear about this subject.
By now, like Age of earth, I need accept this duedate.

the sun doesnt burn, but thats a different question.....scientists think that the sun has a few billion more years before it begins to swell and swallow up the planets out to the asteroid belt. then it will continue life as a red giant for a while and then contract into a dwarf and eventually stop fusing atoms and end its life as a mass of conglomerated elements and just sit in space.

the sun doesnt really burn so much as to give of overproduced NRG produced by fusion. but the sun has enough mass to continue giving off this NRG for 10's or even 100's of billions of years. when exactly it will be destroyed i cannot say. but nobody can really. at least, not yet.

5 billion, 306 million, 247 thousand, 607 years. 4 months, 2 weeks, 5 days, 6 hours, 18 minutes ...... give or take.

the sun re-energizes itself through fusion. the byproducts of the explosions create energy pellets that hit each other and react again. like billions of nuclear weapons going off and causing so much pressure that the pressure explodes again, and again.

As long as it takes to use up all the contained hydrogen within

about 3 hours, quickly but some thermals on :-)
Until it burns up.
