Casper, since the pilot light stays lit, the first thing I would look at is the burner assembly in the bottom of the water heater. You didn't say how old, but if the heater is several years old, there's a chance that the port holes on your burner assembly are clogged.

It could also be the gas control valve on front of the heater. If the burner assembly looks decent when you take it out, I'd start leaning heavily to a bad gas control valve.
