Have a 2001 Chevy blazer sometimes when go out to start it will not start. turn key and nothing still have power for lights, radio etc but will not start. sometimes you can shift out of park and then turn key and it will start right up other times won't start for few hours or couple of days. any ideas? New battery, fuel pump, power steering pump and neutral safety switch doesn't click like starter going out when you turn the key just nothing thank you for any help

 

Use the search feature here. I had problems with my ignition switch that sounds similar to what you are describing. I replaced mine because of random stalling while driving and sometimes the engine would die when going from "Park" to "Drive". No problems since replacement (at least with this problem).
