Why does bryant plus 90 furnace run properly for 7 minutes, then shut off for 22??

Does anyone why does bryant plus 90 furnace run properly for 7 minutes, then shut off for 22?? Then it will run for another 7, and shut off for another 22. Does this all day long, so it takes forever for the house to warm up, here in Milwaukee. I'm leaning toward the pilot asm (which contains the flame sensor) being faulty, but not sure... It is a model 398AAW036080. Any help would be appreciated. Jim
