Force 10 propane oven problem

[Sea Note]

I have an older force 10 propane 4 burner gimble stove. The age is approx 1997 (we think). I am having a problem with the oven bottom burner staying lit. When I light it a hissing/spitting sound comes out when it is lit and then sputters for awhile then shuts off. It heats well when I can keep it lit. Have cleaned oriface as instruction manual instructs and as others have instructed that worked for them. Any suggestions, do I need a new oriface? And where could one get them? i'm in San Diego at this time but heading out to Hawaii on May 8th.

Have you tried calling the Force 10 folks?
