Bosch Dual Fuel Range will not hold heat setting

My Bosch Dual Fuel range, HDI7282c/01, will not pre-heat past 370, and once it reaches that temp. it goes down to 330 (and sometimes 275). I have had one service call where the heat element was checked and a circuit board replaced. It did pre-heat to 350 (which is where it was set) so we thought it was fixed. It wasn't. The range is on a dedicated outlet.
Any ideas?

There needs to be a sensor that monitors the oven temperature and reports it back to the control board. These sensors drift off of calibration as well as go intermittent.

I have no service info on your unit but if it's like most units it's mounted inside to the upper back of the oven and plugs into wiring harness in the back of the range.
