As always, look at the big three factors.

Air
Fuel
Spark

Of course we all know that, but if you believe it's fuel related, look at the cheap stuff first, such as the fuel lines. You may a small split in one of the lines, or the fuel pump may have a loose ground/wires. If there is a split, it could be small enough where it won't spill fuel, however will lose fuel pressure.
