1990 7.3 wont crank sometimes

the other day the truck cranked and ran 10-15 seconds and cut off. after it would not start. after about 2-3 hours i went back out to try it somemore and it started right up.ran fine eversense. it had been setting for about 3 weeks. it has done this before a few times. hot and cold. usally if i crank it and it starts to sputer i give it some fuel and it picks up and runs fine. but other than that it is a great running truck. does any one know what the start up prob. might be. thanks mike

Air intrusion, you need to replace the return line O rings and lines between the injectors.
