2011 Tundra starting problem

I have been having an intermittent problem with my 2011 Tundra 5.7L for about two years now. The problem is that after driving the truck (sometimes a long trip and even on short 5 mile trips) and turning it off if I try to start it again soon occasionally it will not start. No click no noise whatsoever. All the dash lights work windows work everything but it will not start. If I wait anywhere from 10 minutes to 1 1/2 hours then it will start. I have replaced the starter, both 20 amp fuses and the ignition relay but still have the problem Everytime I have taken it to a mechanic it starts fine.
