⚡ Quick Meaning
To run out of steam means to lose your energy or enthusiasm before you finish something.
🚂 Wait... Why Steam?
RUN OUT OF + STEAM
A real engine? ❌
Losing your energy? ✅
Old trains were powered by steam. A fire heated water, the water made steam, and the steam pushed the engine along. If the fire got low, there was less steam, and the train slowed down until it stopped.
When people run out of steam, they are like that train: they started well, but their energy is gone.

🕵️ Where Did It Come From?
The picture is clearly the steam engine, which slows when the fire is too low to make steam. The Phrase Finder website says the figurative use began in the United States in the late 1800s. The earliest example it found is from an Iowa newspaper in January 1898, but that is only the earliest one it could find.
💡 The OddLingo Trick
Think of a toy train that is slowing down.
That is you at the end of a long day. A snack, a rest or a good night's sleep puts more fuel in the fire.
