Stalling car

my 2000 Buick Century stalls for no apparent reason within 1 or 2 miles from start up. It gives no dash light indications of dieing nor stors any trouble codes. it is as if it runs out of gas but when I check fuel pressure at the fuel rail the pressure is ok. After the car sits for about an hour it will start right up and is good for another couple of miles. This has me stumped as I have checked most of the systems. Any Ideas?

If it’s not a fuel problem, it must be ignition. Have you checked for spark when it doesn’t want to run? How many miles on car? Whay systems or parts have you tested and ruled out?
