Ruud Gas Furnace not running up to set temp.

I have a Ruud gas furnace that is 3 years old. The heater ignites and runs for 1 -3 minutes with warm air blowing out, then shuts off. It repeats this cycle until it goes into lock-out. The heater never runs long enough to get up thermostat temp setting.
Any ideas?
