The pilot light & will stay lit. untill the burner cycles on/off
I have a 6 gal hot water heater model no. G6A-7 s/n 96202369825the number on the control device is37C14U-5 the water heater has not been used for the last 6 years. The pilot light lights and will stay lit. And will remain lit after the burner lights and while its burning. But when the burners go’s off the pilot light goes out also. What could be causing this? I have replaced the thermal coupling.

Sounds like it. Before replacing gas control, try removing thermocouple connection at valve and spray electrical cleaner in there and blow out with compressed air after, being careful not to get it in your eyes. If no electrical cleaner, try WD-40 and blow out after. If you twist up a piece of fine steel wool and insert in there as well and try to spin/twist it to clean contact inside may help as well. Blow out goo after and re-install fitting and try again. If that doesn"t work, replace gas control. P.S. Highly recommend certified experienced tech perform this control valve replacement if necessary.
In my first 15 years as a plumber I never saw a pilot light issue on a gas WH that a new thermocouple didn't fix. Since the government mandated a redesign of the fire box, I've seen three that nothing ever fixed - two Whirlpools and one (my usually ultrareliable) AO Smith - including replacing the entire burner assembly and the regulator. And I've heard of many others.
Check the thermocouple connection for tight. (Don't strip.. threaded soft metals.) Check the microvents on the bottom ? of the burn box for dust, even if it is new. Call Reliant and demand new units until you get one that works. Try another model. Consider a 52gal electric.
I've always recommended gas over electric, and AO Smith and Rheem were my recommendations (and "Reliants" were "lumber yard" water heaters. Sorry.)
Since the mandated redesigns, I don't really have a "proven reliable" model to suggest. I increasingly believe the restricted air flow design is the ultimate culprit, including any changes to the thermocouple/regulator construct to accommodate the restricted air flow design. Just my hunch.
