Question about 2000 Buick LeSabre
I'll start by saying folks like me that answer questions are all volunteers. Nobody gets paid. So we pick and choose the questions we answer.
I'm not sure I am following your question / story.
Are you saying the engine will crank but not start sometimes ?
Is the check engine light on when the engine does run ?
Have you checked fuel pressure with a gauge before and after cranking the engine ?
Have you replaced the spark plugs in the past 12 months ?
When the air temp is below freezing it takes twice as much spark and fuel to start a cold engine. So any little problem can become huge.

SOURCE: 1992 buick lesabre starts fine.
You check the coils with a ohm meter. They should 6-8 thousand ohms at the spark plug connections. One lead to one spark plug connection and the other lead to the other . It's not likely a coil for stalling. If coil , Your car can still run on four cylinders. It can be a ignition module. It fails when it gets extremely hot. The module is located under the coils.

i had the same problem on my '92 Lesabre ltd. All you need to do it is get the rust off your battery cables, use the wire brush to scrub the contact surfaces. also use a wrench to tighten the bolt to the battery, take precaution as to not to tighten too much , it might beak the battery threads.

SOURCE: battery drain
Check the (red) + battery cable where it crosses over the metal power steering lines at bottom of radiator....very hard to detect .....over a peroid of time the insulation will wear thru....making contact with steel lines causing a battery drain just as you have indicated...clean cable in this area....use a inspection mirror and a flashlight.....the insulation will be worn off on underside of cable...you will be able to feel worn area with fingers....wrap area well with electrical tape ....Good Luck...

Car not starting or turning over indicates towards multiple possibilities.
It can be issue with battery or weak battery. But if battery checks out ok, then
it can be starter issue or faulty alternator or problem with low fuel pressure
or no spark at spark plugs due to dirty spark plugs or faulty
ignition coil or injectors getting cracked or dirty and needs to be cleaned.
To confirm the problem, the basic troubleshooting is required.
