If I understand your post correctly, once you get the car running, you have no more problems the rest of the day? That would explain why there are no codes. The ECU typically will not react to issues. Unfortunately these are complex systems, and Nissans tend to have some gremlins (I have an 07 FX, and had owned several others).
The easiest thing to check is the battery. The system depends on accurate voltages, so test the battery under load (the standard test won't do). If it's over 3 years old, it might be the cheapest first step to replace it. Keep in mind that both the engine and the battery operate better once warmed, so this is consistent with your "all day" experience.

Also, if you have occasion to start the car then turn it off quickly (like moving it inside at night, you can have unburned gas causing hard starts. This can happen in cases where the engine is run less than five minutes from cold.

Could be pressure valves, check valves, or a number of other things. If you live in a harsh climate, you may be getting some corrosion in the electrical connectors. This can through off voltage and cause the ECU to react to incorrect conditions. If you're handy or have a patient friend who is, the repair manuals have a fairly complete diagnostic process. Also, check the Infiniti forums.

Check the heater hoses if they are both hot (one is very hot the other a little cooler) then the problem is the air temperature control HVAC blend door actuator or the blend door is sticking in the duct it sits in, in most cases the problem is with both parts. In order to repair this the entire dash must come out to access the defective parts. Please have this diagnosis/guess confirmed as this is a very expensive repair.

If you have a check engine light on then you need to scan the codes. Before you do that, check all fuses, powers, and grounds for good contact and make sure there are no loose wires or any corrosion. if fuses, wires, powers and grounds all check out good. then you need to scan the codes and isolate if you are lacking fuel or spark. could be a simple ecu program or security reset. notice the security light when you go to crank it. does it blink, stay solid or flash in any sort of pattern? feel free to call if need be 4 2 3 3 2 7 4 1 0 8 Tim

The problem is the Door lock actuators and when I went to the dealer they want $467.90 to fix just my driver's side door, but after almost having a heart-attack from the dealer's estimate, I checked on ebay and found a Kit to fix the door lock for only $59 so i ordered one kit (shipping was super fast) it came with very easy instructions on how to install the kit, so I installed about 4-months ago in under 1HR and now everything is Back to normal, I can unlock/Lock using my original OEM key fob and also using the power switch on the door, so everything work as from factory ( no need for aftermarket alarm or remote) ... !!!! here is a link of the kit that I purchased. The seller is green-seller1975 and item #111291472359
