Mac G5 2.5 Dual Not Restarting

My G5 2.5 dual, runs all day with no problems, if I shut it down for any reason, I have to wait 15-20 mins before I can restart it. If I start before this period then the machine chime but then hangs and does nothing else, nothing is displayed on the screen. If I wait the 15-20 mins the machine continues to work all with no problems.
The machine is clean inside and the fans run as normal.

Any advise would be great

Thanks

It sounds like you may have a cracked solder trace or some other electrical discontinuity in the power system. My very strong recommendation to you is to take your computer to a repair shop that handles Macs.
