1. There is NO pilot light. That is the regular flame
2. Yes, it could run 2 to 4 minutes if the Thermocoupler was bad, but that is rare. MOST flame sensors shut down after 45 seconds, UNLESS you are not watching and the refer does a triple start. Most refers have a tri start ignition cycle that will light, then shut down after 45 seconds, the wait a few seconds and relight and if it shuts down will wait a few seconds and then try the 3rd time. If no flame sense after the 3rd try it locks out and the check light comes on. THAT can be your 2 to 4 minutes. IF that is not the case, then a flame thermosensor can have an intermittant operation and then shuts off randomly.
3. NO FUSE will cause this problem. It is either the Flame sensor or the main control board. 9 time out of 10 it is the flame sensor, unless you have a Dometic refer built from about 1992 to 1998. Doug
