Universal Heat Death occurs with limitless expansion. Stellar reactions still occur because of the leftover material from the big bang and the relative interaction of all the forces in the universe. If the universe expands indefinetely, eventually everything will be too far apart for anything to happen and yes, literally everything can burn out and entropy into chaos. That's why the Big Crunch idea is emotionally popular because then at least everything goes back into a tiny dough-ball to be thrown into the unversal fryer again to puff up into a delicious Stampede doughnut.
