I believe this is a manual fuel pump and you may have lost the prime, no fuel in hose to tank. If the hose from rear frame to tank has a break or hole, it will **** air and not fuel from tank. If this is not the case, possible clogged fuel hose, tubing, or pickup tube in tank assuming you have turned the engine over serveral times and there is enough fuel in tank. Some tanks do not pickup from very bottom because of water laying in bottom of tank from condensation.
it could be a bad belt or signs that the fuel pump is getting weak put some STP gas treatment in the gas tank make sure you have at least a half a tank of gas before you do this ask yourself when was the last time you changed the fuel filter
These vehicles had issues with fuel pressure bleeding down when they sit for a period of time (like overnight). Nissan has issued a Technical Service Bulletin (TSB) on this issue.
There is a check valve in the fuel pump assembly that holds fuel in the fuel line so that fuel is readily available to the engine. This valve fails and allows that fuel to slowly drain back to the tank. The reason you have to crank the engine for a long period of time is that the fuel has to be pumped from the tank all the way to the engine- may take 10 seconds or more.
Once you start the vehicle, fuel is available and since the drain back to the tank is slow, restarting after even a few hours will be much easier.
The repair involves replacing the fuel pump "module" assembly (it's a service kit that contains the check valve mentioned earlier). The fuel pump assembly is removed from the tank and disassembled and reassembled with several new parts. This is a dealer-only repair. Depending on your level of expertise, you may be able to perform the repair yourself, but will have to buy the parts from the dealer.

I wanted to just give a suggestion...do you go to the same gas station to get gas? My sentra ran horrible because I kept going to this same gas station. My gas would get low and it would start cutting off and trying to cut off. I let my fuel go to almost empty and then went to another gas station to fill up. It hasnt cut of for about 6 months now and I havent returned to that gas station.
if it cranks for a longer time than normal and than it starts, you my friend need a new fuel pump rebuild kit/pressure regulator inside the gas tank. what happens is that the fuel will go back into the gas tank instead of staying in the fuel line and everytime you turn the key, the pump has to pump fuel all the way to the injectors again to get the car started. So, long crank and than start means fuel pump rebuild kit/pressure regulator in tank.
