It's propane only, it will light for just a second or 2 and then kick off and my reset light on my panel comes on . I have reset it several times but it still want work

O.k.,it doesnt like a fuel or fuel valve issue here since it does light briefly but what can cause this is a faulty temp sensor.If the hot water heater temp sensor is sending a false temp signal that it is hot already it will turn off the heater from running.This will then light and go out like you see here.

This will have to be tested further to make sure that this is the cause here and will require the correct diagrams to check this as well as electrical test equipment.I suspect this sensor will need replaced as I have had to do on other models.It is possible the ignite switch is the cause needing replaced but usually it is the temp sensor.
