3.3 V6 Car drives GREAT for 1/2 hour then it starts bucking, has no power than finally stalls. After 15 minutes it will start and run for a short wile until it begins again.
Replaced O2 sensors, fuel filter, spark plugs and wires. I have checked for vaccum leaks\gasket leaks\EGR and find none. Oil is clean as well. NO trouble codes found in the OBD I. I think it is either the coil or fuel pump. Coil costs less so it is next to go. I doubt it is the CAT because it runs perfect when started. Is there anywhere else to look?

The problem was fuel pump (after I changed so much else) I borrowed a fuel pressure gauge from a friend and watched it drop from 46 to 12 psi when warm. Wish I had access to this tool sooner.
