The main relay on my 1993 Accord sure did cause my car to
stop running. I was typically able to restart it in a few
attempts after coasting to the side of the road. The problem
went away after my mechanic resoldered the main relay. The
problem more commonly manifested itself as the inablilty to
start the hot car after stopping for a few minutes.

Noted, though my 91 Civic's main relay never failed while I
drove the car. For a few months, I put up with the
"non-start after driving a hot car and stopping for a few
minutes" deal. A new main relay fixed it right up. (Though
re-soldering is said to be just as effective.)
Tegger's site (which often, but not always, denotes some
group consensus) notes: "Once the car does start and run,
the relay seems to be able to maintain the connection even
with cracked solder, and keep the car running. I'm not sure
why."
Yours may have been a perfectly probablistic exception,
though.

That's decidedly rare. Usually keeps working once the car's running.

Could be the coil too.
How to check:

A "dwell meter" is also known as an "engine analyzer". Availaible
everywhere.

AFAIC, that helps. Said "engine analyzer" is available at
Autozone for a digital version, $80. Available at Ebay,
bidding is at $10 at the moment for a Sears Craftsman
(older?) version that clearly has "dwell" noted on its dial
knob. No idea what the quality of either of these is, but if
the guts of this isn't much more sophisticated than a
digital multimeter, I figure one can't go too wrong with a
cheap engine analyzer. Looks like fun, too...

They were more common in the latter days of points-and-condenser ignition.
Once you preset your points gap to .018", you then fine-tuned it by
checking the dwell angle (hence the name "dwell meter"). You might have to
close the gap up a touch or widen it to make sure the coil was getting
properly saturated.
I fried two cheap dwell meters in 1981. At that same time, I was also
unable to determine why I was suffering severe points burning in addition
to the dwell meter failures (but didn't then know the two were related). It
seems the aftermarket coil that was on the car when I bought it had been
installed upside-down. IOW, the + and - terminals had been swapped. Easily
done, since the terminals were not marked! The garage only discovered it
when they put the car on an oscilloscope as a last resort, and saw that the
sine wave was upside-down.
