It can be anything intermittent. I had a similar problem with my 1993 and found it to be a bad fuel pump relay or maybe the contact in the relay box was intermittent. Anyway, replacing the relay ($4 at O'Reilly) and brushing off the relay box contacts with a wire brush and some alcohol made the problem go away.

This happened to me today. It's happened two or three times in the past year with my 1994 Explorer XLT 4x4. It would crank and catch, but idle slow and rough, maybe 400 rpm before dying. Pressing the accellerator didn't make a difference. No black smoke from the exhaust. So I wondered if it was getting gas, and depressed the schraeder valve on the fuel rail (key off). I heard a hiss like air escaping, and a couple of drops of gas came out.
It then started and ran normally. This makes me think it has something to do with the fuel pressure regulator.
It does it so seldom that I can't really check it out.

I too had a similar problem that turned out to be the fuel pump relay under the hood in the fuse panel. Not sure if this helps but just wanted to make you aware of that device and its importance. When I replaced mine the car started everytime afterwards.

I think you're right. It did it again, and I swapped the AC relay with the Fuel Pump relay. Fired right up.
