The other day I was driving my datsun around and then it just died, It didn't sputter like it was out of gas and the rpm's were fine. After costing to the side of the street I tried to start it back up again, the engine cranked over but that's all. I tried it a couple more times and I got it to start once or twice but both times the rpms would waver and it responded negatively to me tapping the gas peddle, it died after 15-25 seconds. I checked the points and they were fine. The car has new spark plugs (less than a week on the car), new distributer cap/rotor/points (been on there a couple months never a problem), new ignition coil & condensor (ran for about a week with them until this), new water pump, also I drained the gas tank recently (it was clean), busted open the SU carbs they were fine (everything was in working order).
