Hydrogen
Bigger stars get hotter, and use up their fuel much faster than smaller stars.
Yes, red dwarfs burn their fuel slowly because they have small sizes.
Three things are required for a combustion reaction to occur: fuel, oxygen, and heat. The fuel provides the source of carbon and hydrogen, oxygen is needed for the combustion process, and heat is required to initiate and sustain the reaction.
fuel pump
A star dies when it runs out of fuel to sustain nuclear fusion in its core. This fuel is mainly hydrogen, which gets converted into helium through nuclear fusion. Once the star runs out of hydrogen, it will expand and eventually collapse, leading to its death in a supernova explosion.

hydrogen
In nearly all stars, hydrogenis the most abundant element and it is consumed in a nuclear reaction that power stars.
Young stars burn hydrogen (the lightest element), converting it into helium. Later they may convert helium into heavier elements.
For a start, it's the most common element in the Universe. Also, it's the element that most stars use as nuclear fuel, for their enormous power output.
Main sequence star: hydrogen-1. Red giants: helium-4.

The fuel injector provides the fuel. The spark plug provides the fire.
The primary fuel for all stars is hydrogen
The energy in stars comes from nuclear fusion. Hydrogen atoms are continually fused together to created helium and with it, massive amounts of energy.
larger stars have longer lives, because as stars burn they are slowly burning up fuel and begin to cave in on themselves. the larger, the more fuel, the more fuel, the longer lasting.
