2005 Won't Start All The Time
I just recently started having this problem. I can drive someplace turn truck off get back in & it will start while other times nothing. I turn the key & nothing happens no noise what so ever. My radio & accessories turn on. I had the battey looked at. Does anyone have any idea what I can check before I take it the dealship? I have 4.6 Automatic 2005 STX model.
Thanks for any comments in advance.

Well... it could be a faulty starter, something with the PATS or ECU, or else it is indeed a bad battery.
Since it is a 2005, and it is currently 2009, I recommend getting that battery changed. I'm assuming you haven't, by the fact that you said, you "had the battery looked at". I can look at a battery too... and test it, but it does necessarily mean it's good still.
IF you already replaced it recently, then I'd go with taking it to the dealers to have it examined, if under warranty. IF not, then look for the obvious... might be corroded starter wires, might even be with the COPs.
How many miles do you got on this little bugger?
If you got close to 100k, I'd suggest doing the plugs. It's not that hard... but I suggest, if you've never done any mechanical work before, take it to a shop and change the plugs.
But let's start with the small stuff, like replacing the battery, then working your way up.
Remember, even though your lights, radio, and accessories work, DOES NOT necessarily mean your battery is good enough to have the cranking amps to start the engine. Meaning that running your radio is a joke to the battery compared to turning that key to START.

My truck has 27,500 miles on it. I tried jumping the vehicle when this happens but no luck. Also, I have tried putting in neutral & starting just in case the neutral safety switch is faulty. It happens only ride after I drive somewhere & let it cool down for 5 mins or so. Then it starts up, I want to try something before I take it the dealer since it is out of warranty.

I think you have an electromechanical problem vs an electronic problem.
The key factor here is that you are not getting any noise at all. I know the computer doesnt controll the sarter. Does the PATS in some way?
I think you have a problem with the:
Starter - Bad Spot in the wiring
Solenoid - intermittent operation
Keyswitch - intermittent operation
Neutral/Park switch - intermittent operation
I suggest moving from park to neutral if the vehicle wont start. Try that first.
Then move on to starter.
How often would you say that it wont start? If the truck does not click at all, check these items.

If you are getting positive and consistent gear selection, sounds like your reverse switch. If you have a suspension lift, there is no modification to your tranny/cable relationship. If you have a body lift, thats another story.
