well the first thing to do is check the vent system. make sure its clear. this sounds like its overheating and the thermostat is kicking off, does the heat come back on after it cools a while? let me know thanks Bryan, p.s. try running it with the vent off and see if this happens.

Thanks. Vented area wide open no blockage. Dryer runs inconsistently. Runs at adjusted temperature and than goes in to cool cycle. after several hours off it will repeat. Seems as if a timer or temeparture sensor is shutting off gas? there are several timers and sensors that control heat

ok I believe you have bad gas coils in this , this is usually the cause of this problem , these open and hold open the gas valve, there are other reasons such as the thermostats, flame sensor , or igniter but for the most common cause its the gas coils. these are not expensive and you can get them here@ these are fairly easy to replace and heres a picture on where there located Gas Dryer Gutshope this helps, thanks Bryan
