If you have lost this much power, you have lost 120 volts (a leg) of your 240 volt power. You may be able to turn the main breaker off then back on to reset and correct the problem. Also, you need to check that none of the other breakers are tripped.

Is there some history to this occurrence or is it something with no probable cause?

It would be unusual, though not impossible, for one entire side or section of a modular to be fed only from one leg of a 220 volt supply.

Further, if one phase had lost power, the side with the range and utility circuits would be indicating problems also, especially on 220 volt circuits such as those trying to run the stove.

Non-the-less, it would not hurt to have a close look at overhead lines and splices if you are supplied in this manner to see if something looks like it may have come apart.
Is so, call your supply authority.

Check the panel directory. See which circuit(s) supply the side with no power. Try re-setting them. Turn completely off, then back on. If you have a cheap neon bulbed circuit tester, and know how to use it, check for power at the conductor termination points of the circuit breakers you have identified as those supplying the troubled circuits.
Also, after turning the circuits off, see that the conductor to circuit breaker terminations are correctly secured. Turn the circuits back on.

While you are at it you can check to see if both busses or 'phases' have power. If not, you will have to check the main breaker. If a reset with the cover on doesn't work, remove the cover. Check for power on both lines coming in. Also visually check to see that nothing obvious and visible is amiss.

If there is no power at this point, you should call your power supply company. (they may find a problem and remedy it for free or let you know if you need an electrician.

However, it is more likely that your problem is in the residence. Modulars often have connection points, or junction boxes where the wiring from the panel connects to the wires from the separate halves or modules.

It is possible that some splices there have come apart. A visual check and tug test on these wires and splices, as well as some probing with a neon tester may shed some light on your problem. If it is beyond simple seek and checks like this, call a pro.

I hand the same thing happen.  I am a retired electrican.  I pulled out ever electrical power plug and switches that had no power.  The very last plug I pulled out was the one.  It was a plug under the trailer which I did not know was there.
To find this I used  what is call rinning out the wires.  You will need a Volt/ Ohm meter to do this.  It took me about 25 hour to find the problem.  The wire was not pushed in all the way.  Good Luck
