Unknown. Attested from the 18th century. The Canting Academy defines peeter as “A portmantle”; Green’s Dictionary of Slang list a variety of uses for peter – including trunk or portmanteau – in thieves’ cant in Britain, Australia, New Zealand, and the United States. The OED suggests that it may be related to St. Peter being the holder of the keys to God's Kingdom.

The forty quid! Gone! ’Ow could she ’ave gotten in there? The peter ain’t broke, no sign of it bein’ bettied, and I the only one w’ the key. 2013, Zack Wentz, “Simplicity itself”, in Sherlock Holmes Mystery Magazine, volume 10, page 161:
It used to be simple to 'crack a peter'. Safe-breaking (blowing or cracking a 'peter') in the past three or four years shows that the expert cracksman knows his job. 1963, Kenneth Ullyett, Crime out of Hand, page 109:

English peter
Unknown; the following etymologies have been suggested:
* From peter (“to stop (doing or saying something)”) (slang, obsolete, rare).
* Since the word was first used in mining contexts, either:
** from French péter (“to explode; to break wind, fart”) (slang), from pet (“emission of digestive gases from the anus, flatus, fart”) (slang), from Latin pēditum (“flatus, fart”), from pēdō (“to break wind, fart”), ultimately from Proto-Indo-European *pesd- (“to break wind softly”), probably imitative; or
** from (salt)peter, a variant of saltpetre (“potassium nitrate”) (the key ingredient in gunpowder), from Middle English salpeter, salpetre [and other forms] with the first element influenced by salt, from Old French salpetre (modern French salpêtre), from Medieval Latin salpetra, from Latin sāl petrae (literally “salt of stone”) (as potassium nitrate occurs encrusted on some stones), from sāl (“salt”) + petrae (the nominative or vocative plural of petra (“rock; stone”), from Ancient Greek πέτρᾱ (pétrā, “rock formation; stone”)).
Meanings
(intransitive) Chiefly followed by out: originally (mining), of a vein of ore: to be depleted of ore; now (generally), to diminish to nothing; to dwindle, to trail off.
Mersey Street is particularly attractive. Running up from the bay, it passes between terraced cottages before petering into a footpath that leads over the headland to a golf course and the dune-backed sands of Black Rock. 1980, AA Book of British Villages, Drive Publications Ltd, page 73:
I found a veinlet about 15 in. wide and very rich in gold. Trenching along its outcrop showed that it extended about 100 ft. and then pinched out altogether. A winze sunk on the veinlet showed that it "petered out" entirely at 25 or 30 ft. 1910 T. Lane Carter: Mining in Nicaragua. Transactions of the American Institute of Mining Engineers. Vol. XLI. 1910.

Whitney is absorbed especially by Dublin's unglamorous interstitial zones: the new housing estates and labyrinths of roads, watercourses and railways where the city peters into its commuter belt. 2014 August 23, Neil Hegarty, “Hidden City: Adventures and Explorations in Dublin by Karl Whitney, review: ‘a necessary corrective’ [print version: Re-Joycing in Dublin, page R25]”, in The Daily Telegraph (Review), London: Telegraph Media Group, →ISSN, →OCLC, archived from the original on 20 May 2022:
