F-350 won't start
So I have a 2004 f-350 5.4L V-8 gas engine w/65,000 miles on it in my truck, about every 2 - 3 weeks it just does not start. It turns over just fine but acts as if it's not getting fuel or spark I'm guessing. Yes there is plenty of gas in it! :-) I have recently had the entire fuel system serviced with new filter and new gas cap. After that it went about a month and a half without an issue. It's been happening for 5 months or so now....there is absolutely no logic to it that I can tell (weather, engine hot, engine cold), it does not discriminate. The crazy thing is if I come back to it 2 hours later it starts right up. Basically it won't stay broken long enough to take it to the shop.
Any help would be appreciated....thanks!
