Is the check engine light on?
You mention distributor, new including cap and rotor?
Did you replace or perform a resistance test on the plug wires?
Did you remove the plugs and check if any of them look like they are not correctly firing?
Did you perform a fuel pressure test?
How many miles on the engine?
