Lennox 17J57 Ignitor

My heather igniter turns on and starts the burner but after a few minutes it shuts down. I have a Lennox Elite furnace. Is it the igniter the problem?

It could be the ignitor, gas valve or / and some other parts. We cannot pinpoint where the problem is without checking it out in the field. If you are not sure which part is bad you can hire someone or chat with an expert to troublshoot the unit at the link below.
