Our club's PA32R-300 has an IO-540 with lots and lots of hours on it.
seems fine. Could it be vapour lock? Any other suggestions?


Yes...check the electric fuel pump?


As I said in the post above:
Based on a suggestion here, I had them check the fuel pressure, and it
seems fine.


It was 22psi with just the engine driven pump, and 23psi with the electric
fuel pump on.
