I have the exact same problem ...and about the same age...
Heter runs for a few minutes then turns off... the IGN light will light up...
Is there a manual available?
How do you replace the flame sensor?
The flame sensor is easly replaced, but easier to just clean. Only use steel wool never sand paper to clean a flame sensor. Post the exact model and I will publish the manual on my company website and post the link for you to download, print, etc.
manual for your pool heater can be found here: http://www.pentairpool.com/pdfs/MiniMaxC...
If the heater runs for a short time then turns itself off it could be a flow switch or temperature limit opening. The manual does contain the wiring diagrams, but unless you have experience servicing these units, I do not suggest you attempt it but rather call a good mechanical contractor to service your heater. If you post your general location, I can recommend a few near you that have good reps and quality customer service.

It is a MiniMax NT LN Model 400
From Pentair Pool 400,000 BTUs
I noticed what looks like 2 flame sensors. But I do not know how to get them out and clean them.
Thank You for your help!
