Possible vapor lock or heat soak issue ?

When sitting around idling in the driveway the psi was sitting around 7 on the fuel pressure gauge. If the car is having issues getting fuel to the engine if I drive the car and it dies on me I guess I should push the throttle linkage and look in the carb to see if anything is squirting in ? Right now the car is sitting in someone's driveway down the road...
