We have a Senator Virginia series 5. I have only used the oven two or three times and have found that the flame keeps going out. After a few minutes of operation the flame 'leaves' the burner and goes out. The first couple of times I used it I found that, after re-lighting it several times, it then stayed alight, but last weekend it went out again after about half an hour - thank goodness for the built-in microwave! I'm planning to contact our dealer, but has anyone else had this problem or can suggest a fix? Thanks.
