You must have turned the key back on. It is a good practice
to check the P lead grounding on a regular basis by turning
the key off at IDLE to be sure the mags can be killed. Then
turn the key back on before the engine slow too much, no
harm will be done. There is an AD that requires just this
test, BTW.
Then shutdown with the mixture to clear the cylinders so it
is less likely to start accidentally is the P lead/switch is
disconnected.
