1992 GMC K1500 5.7 350 Will Start But Won’t Stay Running.

The truck will start but will only run for approximately 5-10 seconds before shutting down. It takes sometimes 10-15 times of starting and running then shutting down before it will stay running. Almost like its not getting fuel all the time(fuel pump runs when key is turned). But when it finally does run, it runs great. Please help! Fuel filter, fuel pump relay, oil sender/pressure switch have all been changed since this started.
it is a throttle body intake.
