1998 v8 stalling

Started truck and it stalled right away. This happened a couple of times until, then I turned the key and it would turnover but not start at all. I waited a minute, and it finally started normally.

What could cause this?

KM's are at 230,000

any codes stored you could have a bad crank sensor but must monitor many things when the no start condition happens {spark fuel pressure etc...}

fuel pump??
