What causes the engine to shut off while driving?

When the 1992 chevy astro van is started, it will just shut down numerous times even on short trips. But, will restart
on the go then shut down again.

Fuel filter may be dirty if it starts up almost immediately then it may be a really dirty tank causing the filter sock to clog. A filter generally takes anywhere from 10 mins to an hr before restartup. A dirty fuel filter sock can drop the crap almost as soon as the pump shuts off allowing an immediate restart. Hook up a fuel pressure gauge and drive it around with the guage visible from inside. I'm guessing it has a 4.3L TBI in it? The pressure should NEVER drop below 9psi it should stay between 10-13 psi.
