Green’s Dictionary of Slang

peter out v.

also petter out
[orig. US mining jargon, but note peter v.1 ; note Michael Quinion, World Wide Words 14/4/01: ‘There are two possibilities for where it came from. One is the saltpetre (US spelling saltpeter) that was a component of the blasting power that miners used (the second part comes from Greek ‘petros’, a rock); this sounds a bit of a stretch, but you never know. The other is French ‘peter’, which literally means “to fart”, but which I believe has been used figuratively to mean “to fizzle out” (and which famously appears in the English ‘petard’ for a medieval military explosive device, from which we get “hoist by his own petard”).’]
