turns over but won't start

My 1999 f350 with a triton v-10, sometimes when i shut it off and then try to restart it, it will turn over but won't start. If i let it sit for awhile sometimes minutes to hours it will fire right up and i may go weeks before it does it again. Anyone else have this problem or know the fix?

Sounds like the IAC (idle air control) valve is sticking. The next time it does not start, try pressing the accelerator about 1/3 to 1/2 way down while cranking and see if it starts. If so, clean or replace the IAC.

I have some what the same issue. It will start, but only run 2-3 seconds, and then not start again. Does not idle just dies. Then if I wait minutes/hours it will start again, still does not stay running. We put a new pump in last year and just replaced the relay switch. What am I missing?
