Yes, that is what "should" happen. Then again, you should not have
to restart the modem every couple of days. But if the modem is not
renewing the lease, and it is expiring, then a new IP address after
power-cycling the modem would be a good indication.

An IP address that changes before you power-cycle the modem would be
an indication of this, and as you said, time for a new ISP, if
possible. (Some places, you do not have a choice for hi-speed
