SOURCE: my unit sometimes stops playing
No timer issue. I believe thats a thermal problem. After it has been running for a while it might be overheating and shuts itself off. After it cools the thermal switch re-engages turning the unit back on. A few simple things to check are the speaker connections making sure the speakers are connected properly. If you have only two speakers try disconnecting one then the other and seeing if the system still shuts off. If it stays on then you may have a bad speaker. Also make sure the unit has proper ventilation such as making sure its not installed in an enclosure that doesn't have vents. Also make sure there aren't any other components sitting on top or under the unit such as DVD or Blue-Ray players that tend to also run a little warm. Audio amplifiers in general prefer to have at least an inch of clearance above and below to allow air flow. Making sure the unit is clean of dust can be done with a simple shop vac.
If it's none of those things then it may have a thermal issue or electrical issue inside the unit in which case I would recommend having it serviced by a professional unless you yourself are familiar with 110 volts AC safety practices.

You need to resolve it or stop using it as those loud noises are dangerous to your speakers.
Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.
Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.
Check for loose speaker connections at the speaker as another possible root cause for intermittent shutdown.
