The phone will have an algorithm when in a no-signal condition,
to check progressively less frequently (up to a point). This
is to conserve battery, because scanning for an acceptable
network is more "energy intensive" then simply camping on the
strongest cell (and periodically monitoring a fixed number of
neighbouring cells) of an already-registered (and visible)
network.
For this to be the explanation, you'd need to be in an area of
marginal reception where the position of the handset is fairly
crucial.
There could be a number of factors working together against you,
such as some firmware algorithm only marginally adapting to
unusual local conditions. How does the phone behave elsewhere?

I had a Motorola cd928 which would get itself into a state
sometimes where it would never find a signal again, not even in
days, until physically switched off and on again.
This was clearly a bug, but Motorola would never respond to my
queries about the problem, or a firmware upgrade.
It's really a question of experimenting to find the minimal
steps that will jolt it back to life quickly. Perhaps a
"network search" or "choose new network" (but selecting the
existing one) from the networks menu might be easiest if that
works, especially if you can set that up on a key or user menu
(I'm not familiar with that phone).
On some phones, you can set the automatic network search speed
to fast or slow. Fast search should reduce this problem at the
expense of battery life.
Doesn't a simple switch off/on fix it? If not, I'd call it a
bug.

Probably not. Looking for a BTS is fairly hard on a battery, so when
you take the phone into an area without service, it tries a few times
quickly to locate another BTS. After that, it may be 10-20 minutes
before it decides to look again. It is a way of saving battery power.
I used to see that problem in rural Australia. I'd drive right by a
tower, and still see 'no service'. Power the phone off, power it back
on, BINGO!

I can certainly confirm the extreme manifestation of that
behaviour when the reason for the "no service" is an initial
contact with the BTS at greater than 35 km. In the absence of
another BTS, some phones don't try the TA-fail BTS again in the
time it takes to drive the 70 km across its usable range.
I've assumed that this is a result of firmware that's designed
for more populous locations.

Re: Reboot?
My nokia 6256 has been rebooting for no apperent reason when I unplug it
from the charger and close the lid. It's happened like 2 times in the
last 2 days.

As John Henderson wrote, the 'phone will reduce the attempts it makes to get
a signal to conserve battery life, hence the variable times before you get a
signal. To prove it's your service rather than the 'phone can you use a SIM
from a network using perhaps 850MHz to see if the problem remains or goes
away? Or, just try your SIM in someone else's 'phone who doesn't lose
signal within the house to see if your 'phone holds signal as well?
How about and dependant on the weather, sitting outside with the 'phone at a
location where you've just ended a call and seeing if the 'phone loses
signal?

There should be, but.......
On my Palm Treo 650 (GSM) I have the same issue, and I have to do a
power off/on routine, especially when roaming overseas and trying to
acquire a carrier for the first time.
In fact Palm recommend this if there is a problem obtaining a carrier
after turning the phone on, whether roaming or not. Power off again,
then on.
So much for modern technology!

For something as programmable as a Treo, why couldn't somebody write a
"Re-acquire Signal" application and assign it to a seldom-used button? There
has to be a piece of code already in the OS to perform that operation.
