The issue with your 1978 Datsun 280Z starting for a few seconds before stalling could be due to several factors. Common culprits include a failing fuel pump, clogged fuel filter, or issues with the ignition system such as a faulty coil or spark plugs. Additionally, problems with the fuel injectors or a vacuum leak could also affect the engine's ability to run consistently. It's best to perform a thorough diagnostic to pinpoint the exact cause.
Sounds like the alternator and eventually it wont start back up for you
my suburban wont start
There is most likely something in the gas tank. When the car starts the fuel pump starts sucking in fuel and when the trash gets to it the gas will not be able to flow through the clogged pump so the car stalls. When it stalls the fuel pump stops suction and the trash comes out allowing it to start again.

have a 89 Chevy astro van starts good till warms up the start to chock and then stalls
There's a solinoid in the transmission.Suggest to check that first. Turn on interior lights. Start engine. If the lights go out when the engine stalls, you have a bad ignition switch.
Your idle air controle valve.
Could be faulty ignition coils especially if engine starts when cold then stalls and will not start once warmed up.

Start it up again.
Check for vacuum leaks.
Have a similar problem with my forester 1999.
