Possibly coils but not likely. Usually coils fail to to open the valve, I haven't seen them fail while the flame is on. You need to see what is shutting down the burner. Monitor high limit thermostat and see if it opens when flame goes out, when it cools off it will close again. Also check for 120 volts to burner assembly when flame shuts down. I think you will find that something is cutting the power off the burner assembly.

Try it with the vent hose NOT connected. If it works normally your vent is plugged up and needs cleaned out. I would replace the coils while you are at it.

Ok I disconnected and it seem to run fine. I replaced and cleaned the vent line. When I reconnected it made it through half a cycle and now the gas valve does not release could it all be related to the valves?

seems to be related to the Vent

 

Dryer Vent 4" diameter

Vent should be rigid metal.

Short lengths of flexible metal may be OK, if not crimped when moving the Dryer into place.

NO plastic

NO PVC

NO screws

Foil Duct Tape is OK.

With an empty load, Timed Dry, High Heat, the vent temperature should cycle somewhere between 135F and 160F

Check / clean the Dryer Vent

Disconnect the Dryer Vent and check for good air-flow there and where it exits the house.

Check the Vent air temperature at the back of the Dryer.

If you have a Harbor Freight Store near you,

$ 3.99 sometimes on sale for $ 2.99

the temp seems fine. I watched the flame run for about 20 mins and then left the dryer running. When I came back the flame was out and it would not relight. the ignighter would light but the gas valve would not release. Its almost like it cools down and then it will work for another 20mins?

90 seconds

about the correct time for the Flame (heat) sensor to detect that the Ignitor is up to temperature,

The Flame Detector Switch should then open the Gas Safety Valve ...

The valve coils are failing from thermal fatigue. They'll work a cycle or two then stop from heat deformity.

Replace the coils and move on.
