77 corvette; engine hunting or missing after 20 minutes of running?

by Alastair

I can run my 77 Corvette for 20-30 minutes then it starts to miss or hunt. It is still drivable while the car is doing this, it just drops slightly in power. I have checked the fuel filter and pump and they seem to be fine. I put new plugs in and it didn't make any difference. Carburetor is clean with no leaks. Since this miss has started the idle seems to be a bit higher at 1000 rpm. Also, when the car is hot it takes a lot more cranking to start it (about 4-5 seconds). It has electronic ignition so I'm starting to lean toward a problem inside the distributor? Can someone help please.
