My 4 yr old Kenmmore Gas range started acting weird yesterday.

Set it and it would come up to temperature-- but wouldn't maintain the
temp-- it essentially just went off, though the indicator light stayed
lit.

I cooked a roast by turning it off and back on every 15 minutes or so
for a couple hours.

I ordered a $30 temperature sensor from repairclinic.com. It will be
here Wed--

Just wondering if anyone has any other thoughts in the meantime.

Thanks

Now that you've included that it's a gas range, that brings up a whole
new batch of possible issues. If it's coming up the the correct temp and
then shutting off, the temp sensor is ok. Is this a pilot type or
intermittent ignition type of oven? Your issue here would seem to be in
getting the burner reignited when the temp has dropped by the hysteresis
amount.
