Pilot Light on Water Heater Not Staying Lit

I have a whirllpool Flame Lock gas heater model BFGlF404S3dHOV and it will light at first heat and then the pilot goes out. It will not stay lighted after heating the water.

some other possibilities...
The Pilot orifice could be resticting the pilot flame output enough for the draft created by the main burner to pull the pilot flame away from the thermocouple, which then locks out the pilot. This usually happens after the main burners shut down.

The thermocouple is not in it's proper position in relationship to the pilot flame. (Not fully enveloped by the pilot flame)

If this unit has flame quard technology, then make sure the air intake into the burner compartment is not covered with dust.

Condensation dripping on the pilot. Any water stains below the pilot?

Bad business for someone to charge another forum member for advise they give. This is solcitation and I think it is not allowed on this forum, especially if you charge a person for giving information. Am I correcte???

I was thinking he meant on another site where you might pay a fee to get advice.
