What would cause a 2000 Chevy Astro van to hesitate to start but run and operate fine once started?

Probably fuel pump bad check valve allowing fuel pressure to bleed off. Try turning key on and off about 6 times (each time you turn key on the fuel pump runs for about 5 seconds) and see if starts faster when engaging starter. If so then replace fuel pump should fix it. If you can pull the "dog house" the fuel line on rear of engine has a guage port. Put a guage on it overnight and see if pressure is gone next morning. Pressure should hold overnight if check valve is good.
