I have a RUUD (RHEEM) WeatherKing Model # 80PS07EBR01 (Installed in 2008)
It is short cycling several times before it shuts off completely.

Induction motor kicks on. Burner ignites. Blower comes on anywhere from 1 second to 30 seconds, then shuts off and repeats. Sometimes it will finally run and heat the house. Sometimes it just gives up and stops trying. Then I have to unplug and plug the furnace back in.

So far, I have replaced the: (part #)
thermostat
Ignition Igniter (62-24164-01)
One of the Limit Switches: SPST N/C Limit, 160 Open, 140 Close (47-25349-01)

I purchased the SPST N/C Limit Switch, L105-10F (47-22860-01) and the Limit Switch, L250F (47-22861-03) I have not replaced either of these yet. Not sure if either of these is the issue or if something else could be the problem.

Any Ideas?
