Sounds like a battery issue. If it uses rechargeables, it's possible that they either need charging, or if they're old, replacing.

SOURCE: No power on light

That's interesting.. After researching that model I can tell you that it has an intergrated internal power supply(transformer) which does contain a fuse. It is located where your power cord plugs into, inside the unit, start with that. Was it plugged into a surge protector? When you had the power failure the second time was there a fluctuation of power, ie your lights in your house flickering on or off or increasing, decreasing in brightness? This will help me determine if it's something else. Also be sure to check your power cord, look for any kinks, breaks, chips in insulation. Anyway Good Luck

SOURCE: Shuts off

Brian, you have a system failure in your audio amp section. this is a multiple channel amplifier and you have to get it checked only by service personnel. your power outputs transistor probably busted and your unit wont stay because that is your protection circuit working. it protects your unit from further damage.

and for the other comment, your unit will shutoff after long epriod of time at 70%, you need more ventillation to your unit. i would suggest that you use a small fan or blower and place on top of the unit. this will provide more air circulation to your amplifier. The units is tripping already at high temperature and 70% is already a long way to go at more than an hour with all channels working. adwditional ventillation only will help you. dont let it happen though always or it will damage you amp and end up like the later unit that turns off after few seconds. busted output stage already.

Runs when start button pushed for several seconds then shuts down. Starts with button, but when button released, shuts down right away.

Odds are that the ignition switch or wires are giving you the grief.
Thee unit will probably be getting spark power through the starter solenoid (look for a wire there) but when the solenoid is not activated, there will be no ignition power.
Take your time and trace it down.
You'll get it.

I need to know how to reset my printer, I 've cleaned the pads, but nothing... Thank you in advance...

Power down the Canon Pixma IP4300. Once it has shut down, leave it off for a few moments.
Hold down both the "Resume" button and the "Power Button." When the printer begins to restart, release the "Resume" button but continue pressing "Power."
Push in the "Resume" button twice, then let go of both the buttons. In a moment, a green light flashes a few times.
Press the "Resume" button four times once the green flashing has finished.
Push the "Power" button again until the printer shuts down. Wait a few seconds, then press the power button again to restart the device. The Canon Pixma IP4300 will now function properly. for more information hope this helps you.
