No crank when warm/hot
 

Recently have had issues with my 2008 Sentra starting. First time was dead battery, replaced that. Later, starter would only click when the ignition switch was on. Replaced the starter. Both of these resolved the issue for a couple of weeks. Now, if the engine is cold, it starts fine. If you drive it enough to get the temperature up, the starter will not even turn over. Plenty of power on the dash lights, gages, radio, etc. They starter simply will not turn power up. Let it rest several hours and it works fine. The temperature may be a red herring. What features would cut the power to the starter?
