I found it! I was reassembling the stove, I had checked and cleaned all the orifices, etc, the last thing was the burner and I discovered a spider's nest! No spider or younguns' just a small solid web. Cleaned it up and fired it up. Worked great.
All my Coleman stuff: Stoves, lanterns, heaters, etc., are all propane. Wouldn't go any other way.
Happy Trails!
