I have a whirlpool gas stove that has a strange problem. The model number is GS440LEMT 2.

The oven will work normally for a time, then stop.

When the oven stops, the control panel goes dark, and does not respond to anything. The stove top and sparkers still work though.

If I unplug it, then plug it in, the board comes back, with a "PF" (power failure) message. I press cancel, and everything goes back to normal. The clock does not seem to keep time during this "dark control panel" episode.

I then run diagnostic by holding the cancel button for 5 sec and am given a E-1/F-5 which, according to the stove's tech sheet is a failure code for the door latch.

I clear the code (how can one be sure that it is really clear?) and test the clean cycle (which I never use). The clean cycle starts, and the door latch securely locks the door. The control panel messages indicate a locked door and active clean cycle, the gas comes on and ignites. I cancel the clean cycle, the gas turns off, and the latch opens.

I have not let the temp go high enough in the clean cycle to test the latch temp fail-safe, but the latch definitely latches and unlatches.

I have good 120v at the outlet, and the power cord is in good shape. The wires and connections at the back in the control panel area are clean and in good shape, and do not seem to be loose.

There are mouse turds, so a mouse might nest in the insulation, but I haven't wanted to disassemble the whole stove to check the latch mech, since it still works, with out seeking some guidance or advice.

Anybody have any ideas?
