I'm asuming you have a electric furnace.



Check for restrictions in the duct work which might reduce the volumn of air circulating through the unit. Check the filter first, then the A/C coil. If the coil is stopped up you may want to call a service man to clean it (you can do it yourself but may require removing some ductwork to get to it, and the coil cleaner solution is caustic).

As a safety feature furnaces have a high heat limit switch that opens when things get too hot. It works like the one in your blow dryer; if you block the air flow, the blow dryer will overheat and stop, until it cools down.Our Central heating wont stay on we changed the fuses in it and changed the thermostat and the air conditioner
More information, such as the type of system and what exactly is happening is required. For more info including a step by step troubleshooting guide, check out the furnace page at my source.
