94 Pathfinder starting troubles
 

My Pathfinder will not start and run all of the sudden. The fuel pump is working fine it seems. I just replaced the fuel filter a month ago. Battery, spark, module all appear to be good. It cranks like it should and there was no symptoms of anything failing slowly. It was fine earlier in the day. I drove it about 200 miles, shut it off, an hour later, It won't start. :confused: Need suggestions...... Thanks.
