Question about Cars & Trucks
There could be multiple issues here and it's hard to say without really looking/running numbers - is there power (lights/dash symbols/etc) when you turn the key? Or completely dead?
If completely dead, did you see a random brake light while driving? That could indicate a bad alternator. Does jumping it start her? If so, possible you have a parasitic draw in the system draining the battery.
Ground wires are important to check, also.
Off hand, without much data to work with, mass air flow sensors can cause a no start - try unplugging this and starting. You can also backprobe to test sensor and harness for ground. This may not throw a code right away.
I see "sometime," so if assuming a start at times and others not randomly - recheck ignition switch assembly wires, follow them and see if any are loose. A friend had this issue and found the ignition switch assembly wire coming from the alarm was loose.
No codes and random starting, I'd lean wiring. Maybe retrace your steps - it sounds like you tackled the more indicative issues already.

SOURCE: 95 F150 wont crank
the starter should be replaced. The solenoid is kikcing the pinion out but there is no contact being made to turn the starter motor. I have the exact same truck and before i changed the starter used the old starter tap trick. Tap the starter casing with a hammer and it should start turning again. hope this was helpful for you. Good luck.

Today 11-12-08 my 2003 H2 Hummer would not start. Checked battery it ischarged. Cables tight. Tried to start with portable booster pak. No go. Tridto jump start with my wife's Suburban. Still no go.
When I turn the switch I hear a single click and that is it. No engine turning over. While trying to start with key the headlights go out. Out of ideas, Will take to Chevy garage in am. Will post solution.

I had same problem w/ my '88 Ram50. Turned out to be bad contacts on the battery cables. Temp fix and test was to put a little screw between the post and the end connector. Didn't have a problem then, so I replaced the cables.
