When I preheat to 350, the oven warms to 350, the preheat beep goes off, and the oven works just fine.

However, when I preheat to 450, the oven hardly warms, the preheat beep does not go off, and the oven will stay in preheat mode forever.

At this point, if I try 350, the oven will not work.

If I wait a day, and try 350 to start with, the oven will work at 350 just fine.

The broiler works. The burners work.

Should I replace this?

It is 15 years old.

I'd ohm test the oven sensor first. To do that just pull your RANGE out from the wall, then unplug it from the wall, then take back access panel off and you will see a connector that goes to it, remove the connector and ohm test it.

Here's the oven sensor for your model:
Oven Sensor 316233902


Watch this video to ohm test it:

If the oven sensor ohms good, then it would be a bad clock oven control board.

Here's the clock oven control board for your model:
