furnace keeps trying to relight

______________________________________________________________________ I have a janatrolgoodman furnace (GUE120-5)that keeps trying to relight. What happens is stat calls for heat, igniter lights pilot, burner goes on ,blower comes on. After about a minute or two the igniter starts going on causing the burners to shut down. some times it will relight doing this all over again. I have replaced the flame sansor and tried a different stat. This has me puzzled, thanks for any help.
