truck wont start

What is your question?

i recently had the water pump and fan clutch replaced after overheating. that night it started up right after fixing and ran great. i stopped and turned the truck off and it wouldnt start. the truck sat over night and started in the morning. this was a few weeks ago, last night after work i started it up for about ten minutes and turned it off. came back an hour later and it wouldnt start. battery is fine and is getting good ignition but wouldnt turn. woke up this morning and it started first try. Now, nothing
