Burner suddenly quits after 1-2 minutes

I have the Coleman model DGAA077BDTA Gas furnace. We have been having this problem off and on since its first winter in 2002.
The light says combustion failure yet it does indeed light. It will light, heat for about 2 minutes (sometimes) and then just go out. During the winter of 2005 it was recommended here that we try the flame sensor which I did. This did nothing to remedy the problem so we had our propane gas supplier recommend a service company. The company kept promising but never did make it out to work on the furnace so we ended up going thru the balance of 2005 and all of last winter with a full 350 gal. tank and heating with electric heaters. Actually saved money though. We have called another company from about 40 miles away now and they are having trouble diagnosing the problem. It still says combustion failure, still lights, goes right out, tries 2 more time and gives up for awhile. They have replaced the gas valve, flame sensor again and cleaned (didn't really seem to need it) the fresh air supply from the roof. We are waiting for them to return tomorrow for the 3rd time after supposedly going back to the shop to consult with Coleman tech support. I'm doing my best to not short change their efforts and I do believe they are trying their best. This company has been in business here in North Georgia for over 40 years and the founder DOES answer our calls. I guess I'm just getting a little frustrated after having trouble with this furnace for the first 5 years of its use. I was hoping you may have some helpful suggestions as to what I may ask they check if they don't happen to think of it. Is it possible for them to by-pass the flame sensor to verify that it is indeed working or that we may have just by chance gotten 2 bad replacements? Our gas supplier doesn't need any help with off-site storage and that is starting to seem like what I doing with enough gas to keep our kitchen range supplied for 40 years just sitting out there in the ground.
Thanks very much for any suggestions you may be able to offer.
