CHEVY ENG WONT START AFTER SHUTOFF

1999 Chevrolet Blazer

Engine Mechanical problem
1999 Chevy Blazer 6 cyl Four Wheel Drive Automatic 138000 miles

after driving for awhile and then shut off, will not start. Turns over fine. After sitting will restart. Especially over nite. Seems to be fuel prob. Have injected sys. If small amount gas poured in on top of butterfly engine starts till fuel gone. Seems to be related to time engine running before shut off. Switched fuel pump relay in fuse block with another of same type and made no difference. Fuel pressure seems ok when running. My only transportation so being unreliable is real prob. Had prob a year ago with no acceleration after driving a few miles, then shut off and restart. Diagnostic tools unable to pin point prob. Discovered on my own that unplugging 02 allowed normanl operation with eng serv lite remaining on but able to drive. This is not a full size blazer I s the s-10 blazer

Have you checked the fuel pump pressure?
