It almost sounds as though you are experiencing vapor lock. Have your vehicle checked for fuel pressure ratings and see if they meet OE specs

SOURCE: car wont star after a drive
YOU HAVE DIRTY FUEL INJECTORS.THEY ARE STICKING OPEN. FLOODING THE ENGINE. WHEN YOU TURN IT OFF.FILL GAS TANK UP.PUT A BOTTLE OF PRESTONE FUEL INJECTOR CLEANER IN GAS TANK.
SOURCE: starts but wont turn over
I'd check fuel line pressure,,Fuel pumps go in strange ways
and have fooled lots of people, make sure you know what the correct pressure is as it vary's from model to model,I had a Cadilac that blew me away as I thought it was ok only to find it did have wrong pressure,,replaced and runs good after that,,also if you have lots of miles on this car it could be catalatyic converter is plugging up,,notice the exhust output see if it is coming out both tailpipes ok

SOURCE: 1996 Buick Park Avenue, runs fine but sometimes
sounds like a battery terminal ,or earth connection from battery to chassis ,or where the power is picked up from which is the starter motor terminal ,sorry i am not very explicit but i live in spain and not may buicks to the euro here,But if i got my greasy hands under the bonnet i could no doubt find the problem
SOURCE: wont start, had batter checked,
hello Aijalon.
From your description of the problem I would say there is an intermiitant electrical circuit that is staying on and draining the battery.
If after the boost it continues to run the alternator is fine.
When I see such a problem in my shop I instruct my customers to try and pay close attention to doors firmly shut, looking for light from the glovebox, trunk and making sure the interior lights shut off.
I had a Buick in on Friday that the air suspension compressor stayed running due to a stuck relay.
A month ago it was a rear defroster button sticking on a Chev.
A relay or switch could stick for many such devises.
With a problem such as yours working along with your mechanic will be beneficial.
If you have further questions regarding this please ask me here.
Thank you for using FixYa.

??There are two types of DTC's, 1 trip DTC's and 2
trip DTC's
??A 1 trip DTC is for a condition that requires
immediate attention such as a catalyst damaging
misfire.
??A 2 Trip DTC is one that a condition must be found
during 2 consecutive trips such as an EGR fault.
??Most Monitors do not set a DTC and light the MIL
when a vehicle fails a test for the first time during a
DRIVE CYCLE. If a test is failed on a second
consecutive DRIVE CYCLE the MIL will light and a
DTC is stored in the vehicles powertrain control
module (PCM).
