My camaro will start to stall after a couple hours of driving around. The first time it happened in a parking lot and would just not start unless I let it sit for a couple minutes so I replaced the fuel filter. It went on for a couple days with ought it doing it then just started to stall out of no where and wasnt accelerating I then replaced fuel pressure regulator. The psi was below what it should be so when I put on the new one it went up 4 psi I don't want it to stall again and waste money on another pointless part im wondering could be causing this?

Sounds like you have a bad fuel pump and it's causing vapor lock. 4 PSI on even a carbureted system is quite low. It should be a bit higher. Injected systems may want fuel pressures up to 40 PSI and more.
