jennair oven display goes out and oven just clicks

this just started happening tonight.
turned oven on to 325 to cook some ham, about 30 minutes latter i noticed the oven was just clicking and the diplay was blank, then everything started working fine for about five minutes then it started clicking again, this cycle of five minutes on and five minutes clicking has been going on for about 30 minutes. the oven seems to be holding temp at 325, but obviously with christmas coming up i want to know if it going to break down completely.

any thoughts or checks to do would be greatly appreciated
