Thanks Bruce, I did think that may be the problem.
I'll look around for a power supply later when time allows.
We'll close this issue now.

Flaky PS, almost certainly. The ‘I have to wait until it starts again’ is very
diagnostic. You can mod a modern ATX power supply to work:

Bruce,
Thanks for the link, I'll follow it through as I can - the slowness is because
whatever I do results in shutdown and then the G4 won't start on the power
button unless some time has passed (the fans start and the dvd slot clicks
followed by shutdown), maybe two hours left alone - that is the only timing I
have so far.
Restart and sleep result in shutdown, attempt to start with commad-option-P-R
also results in immediate shutdown, and the same if power button pressed
(without pram resetting) soon after shutdown.
However, the power button gets it started when pressed after a couple of hours
have passed.
Last night I deleted the preference files noted in the link - could not restart.
This morning I have managed to reset the pram - and it has just shut down again
as I write!
At least the mac mini is going strong!
I'm thinking, from the delay, maybe a capacitor or similar is at fault?
I have just hit the power button and it is now starting with only a short delay
- maybe progress is being made!
If I get it fixed I'll let you know - if you don't hear from me it is because I
have let it go - it is only a backup mac but I would like to have it working
(and sleeping).
The screen has just blanked, followed after about one minute by shutdown.
Regards
Ged

Hi all,
Quicksilver 2002 800 single cpu
Mac os 10.4.11 Tiger
172GB startup drive
280GB additional data drive (not part of startup user but includes another user
also on Tiger)
Recently this G4 has decided to shutdown when requested to sleep.
Occasionally it shuts down when not requested (while not working/active).
I have replaced the battery, tried different startup drives, and…
First step: try resetting the PRAM : start up while holding down
command-option-P-R and wait for the third startup bong before releasing it.
ISTR fixing one of mine that was shutting down like this by clearing the PRAM.
There are also some system prefs files to delete listed here, but I'm not sure
whether all of them exist in 10.4 or not…
