Starting Problem on 1992 Buick LeSabre

My 92 Buick Lesabre has a starting problem. I can drive somewhere, turn the car off and it won't be able to start again for 45 min to an hour. I replaced the battery, alternator, and the starter. Still having the problem. What could it be?

What are the symptoms when it doesn't start? Does the engine crank over? Does the vehicle have power? Is the battery dead?
When turning it over there is nothing. I have power dash lights light up. Battery is not dead it is brand new.
