There can be various reasons for the flame to shut off prematurely and it will vary with different models. Unfortunately without a model number, I'm unable to access any information about your furnace. However, the thermostat is the usual reason, for this to happen. Turn it up to a higher setting, to see if the furnace stays on longer. Sometimes the thermostat just needs to be recalibrated and sometimes, it needs to be replaced. This can also be caused, by one of the safety switches. If a safety switch is the reason, then it needs to be determined, if the switch is faulty or if there is a reason, for the switch to shut the flame off. I recommend having a technician check and make the necessary repair. I'm listing a site you can check to have a technician come out. Here is a link for the website:
