Suburban furcance prob lem

My furnace will light and run for about 5 seconds, then quit for maybe 30 seconds and try to light again. It does this 3 times then shuts down. You can turn off thermostat and it will cycle and keep on doing the same thing again.
Have you had this problem and want what was done to solve problem and get furnace running again
Thanks

Additional information: Trailer is only just over 2 years old, so furnace is out of warranty. In that 2 years we have camped say 65 days and maybe used the furnace 15 or 20 nights.
I did one test of the furnace where I turned on all three stove burners then turned on the furnace to see if gas pressure would drop. but when furnace lit for a few seconds, gas flames on stove never changed. So I do not think it is a gas or regulator problem.
