As that would more likely occur when the car is just stopped and the carb is sitting on a still hot engine. Hard starting makes getting around difficult. If that check valve is leaking causing the rail to loose fuel pressure overnight that would explain his extended crank time.

Could be a dirty fuel filter or bad check valve allowing fuel to leak back into the tank. 99 chance its your battery since theres also no lights or anything else. If you can crank the engine for 15 seconds its not a low voltage issue.
