My hummer sometimes will not start like it doesn't want to fire up. Wait 10 min and it starts.

I would say the fuel pump is a good place to start. sounds like its not building up good fuel pressure.

to test the fuel pump/filter, have the truck off, then turn the key to acc/lights come on, but not the engine, some models you will hear a low gurgle sound, for a few seconds, turn the key off, then repeat the process again, then off, then start it, to see if the system is just needing more pressure to be primed...
