There are quite a few possible reasons. I would start with the following three:

• Your Crank or Cam sensor is poor/bad.
• You are not getting enough fuel fast enough - perhaps your fuel pump is weak or the fuel filter is clogged.
• Your battery and/or the alternator, or the associated wiring are at fault. The best way to diagnose this is to measure "battery voltage" and "starter voltage" when cranking. The two voltage should be about the same: a) If same at ~10V, your starter is at fault; b) If same at ~6V, your battery is at fault; c) If not same, you are loosing voltage somewhere - bad wiring, corroded contacts, etc.

Start by checking out the sensors, and cleaning their contact surfaces and electrical connectors. This looks like the most likely cause.

Try letting the key sit in the on position for about 5 seconds and then try starting it. I believe the Sentra had a fuel pump issue where the pressure regulator would not hold pressure overnight or at all.
