1999 Cadillac Escalade Question: engine Stalls randomly,and It does crank over.

Is the fuel pump randomly bad then good? Cause if I wait awhile, could be 1hr or 3hrs.. It starts! Is the emission sensor a culprit To this problem? -
Answer 1
Could be a fuel pump; Several years ago had one doing the same thing. Tested the ignition system, computer system, no problems, still died while driving. Finally attached a fuel pressure gauge and took it for a ride. Sure enough the pressure would drop and the engine would die. Pull over and it would start right up with good fuel pressure. Drive a little more and pressure drops again. Changed the pump & filter, no more problems. -
