Heats for a while the makes a noise and stops heating
Dryer heats up then after about a half hour it goes cold. It also makes a rattleing noise when the igniter comes on. At that point the gas valve must not be opening because the is no flame. Could this be the gas valve or something else. please help

Re: heats for a while the makes a noise and stops heating
You don't provide me with a brand, or model number, so I can only give you limited information. Fortunately, most gas dryers have common similarities in this regionIf your ignitor is coming on and no gas is being emitted, then you most likely have a gas valve solenoid failure. Below is a link to a parts breakdown with imagery and installation help. Item# 3479
Always make sure the power and gas is off before servcing! http://www.repairclinic.com/SmartSearch/smartsearch.aspx

I guess I wasnt clear enough. The dryer works ok, except for the rattling sound now. It will start when i push the start button, it heats, and dries the clothes. Just noisy where before the flow sensor went off, it was pretty quiet.
If you are having problems with your gas dryer not heatingthe most common problem is that the ignitor goes bad. Even though it glowssometimes it is still not working properly.
if you dryer is gas check out this gas no heat tip....
If you have an electric dryer, you can have many differentthings that can go wrong causing the dryer not to heat.
check outthis electric no heat tip...
If this is a gas dryer, you probably have bad valve coils, they can work intermittently, usually for the first part of a cycle, but when they heat up the internal resistance gets too high and they fail to open the gas valve. Once they cool off, (by continuing to air dry) they will work again for a few minutes. They will also make a buzzing/rattling (maybe "metal" ) noise as voltage is applied. For any Kenmore gas dryer, get part #279834 it contains both valve coils. Very easy to replace. Another possibility is that your duct work is plugged, check airflow. Hope this helps.
