Check the fuel pump relay connections, the Explorer is bad about connection corrosion at the relays, try unplugging it and sticking it back in. Hope this help, let me know.

If you disconnect fuel line on 2003 ford explorer, should the fuel pupmp shut off if the key remains on

Yes, it will only cycle on for 10 seconds before the relay shuts off. That is called priming so pressure in the fuel system will be at the proper pressure for operation. The fuel pump will engage when cranking engine over but it will create a very huge mess.

1999 Ford Explorer Sport Starting Issue

It sounds like the pump is failing. That or sometimes not getting electricity. To check which it is, you could use a voltmeter or test light at the gas tank's electrical plug in. You need to check for power on the fuel pump wire when the engine is being cranked for starting. Do this when turning the key to on does not cause the pump to turn on for 2 seconds as it should. The fuel pump has power for those 2 seconds when key is turned to on, and again has power when the engine is cranked. You might miss the two second signal, so check for power when car won't start-when pump won't turn on-and with the engine cranking. If you have a signal then and still no pump coming on, then you must have a failing pump.
But if you have NO power to fuel pump wire with engine cranking, then it is a problem elsewhere-probably the pump relay (try a new relay if you haven't already). That relay is signaled by the engine computer when key is turned to on or when engine cranks . so you could do some testing at the relay if needed.

You mean that the starter is turning (cranks) the engine but the engine won't start? Be sure it is getting fuel. Turn the key to the on position and you should hear the fuel pump in the fuel tank run for a few seconds. If so that is good. If the fuel is being delivered then possibly you have no spark which usually is the electronic ignition module. The only way to test it is to replace it. Your timing chain or belt could be broken or "jumped" as the third possibility. I am leaning toward ignition module being bad as they just die without warning and nothing can revive them.

Have 1999 ford explorer V8, Starts 99 percent of the time ,but every so often it just won't. Crank and crank just nothing, won't even fire. Let it sit for ten minutes and wow starts right up. Any ideas?...

Sounds like the fuel pump is going out, you can be tested by placing a fuel pressure gauge on the the fuel rail, run the engine and fuel pressure should maintain around 60psi for approximately 60 seconds after being shut off.

My 98 ford explorer intermittently will not restart after being driven a moderate distance (5-25 miles) and turned off (ie a trip to the airport or store). The engine cranks but doesn't seem to be getting...

If it starts from cold there is no issue with fuel lines or pump. I would check the obvious; fuel to plugs, (damp plugs) and ignition spark.
I assume it is a petrol engine.

98 ford explorer cranks but won't run.

it means that the key(s) needs to be recoded to the car,when you did the wheel you wiped the codes out.....the transponders are in the keys.
the car thinks its not you/your keys.

Ran out of gas in 98 explorer and now wont start with gas was running fine

Check the following: Turn the key to the on position (so the dash lights go on, but the engine does not crank) and listen for a 'whirring, or humming' noise coming from the gas tank. This would indicate the fuel pump is working. You should hear this for about 5 seconds. No sound, you may have a bad fuel pump. The gas in the tank keeps the pump cool, if it overeats it can fail. Change the fuel filter. It is possible you just drew in sediment from the bottom of the tank, and it is plugged up. If this doesn't fix it, let me know so I can help further.
