I have a 68 Supreme with a 350 Rocket . Ran great in the fall . Pulled it out and drove a bit. Stalled at 2 lights.. was really hard to restart. Starter kept turning and turning . Got to destination and when I went to leave battery was dead. Gen light stayed on.. Replaced battery. Also replaced starter . Battery kept going dead .. replaced alternator . Went ahead and changed oil and plugs. And horn relay. Gen light went off. Drove today and did fine .. started to bog out while ideling.. .reved in neutral..and kept going. Next light it died. Tried to restart and it would crank and crank..after sitting a bit ..and mashing gas it started . Drove enough to get home. Any assistance at this point would be super helpful.
The car looks nice. Does it still have points? Rough running and stalling can indicate tuneup time.
Off the tender it starts and runs fine. I changed plugs. It's almost like it doesn't get fuel . But when I go to crank its almost likes its flooded. After I sit for a bit it'll crank if I keep on the gas . And wouldn't have stalled if I didn't have to stop. Still has the Quadro on it
Check for vacuum leaks, especially the hose going to your brake booster. I've seen it where it runs fine in neutral, but when you put it in gear, the engine tilts just enough in its mounts to open up a crack in that hose and result in a big leak and a tendency to stall.

Nice looking '68 BTW.
I'll check that. I appreciate the response . And thank you..
Any assistance at this point would be super helpful....
Yes, we need more info... and not to be an AH but you need to stop throwing parts at it and do some investigative troubleshooting. It's either fuel or electrical related. Hope you kept any original parts you took off?
Points or electronic distributor?
Carb? Q-Jet or? 2 or 4 bbl? Age? Ever been kitted(rebuilt)?
Gas fresh?
What is the running voltage at the battery?
You are gonna need some basic tools:
Vacuum/Fuel gauge.
Volt/Ohm Meter.
Spark tester. Install it on one of the driver's side plugs and run the car. Test drive. When it dies crank it and observe the tester. Flashing while cranking? Yes...sparks there.
Now, look at the carb. Are you getting a good pump shot (Squirt) out of the accelerator circuit? Engine off looking down the primaries actuating the throttle... No/Yes?
Is the fuel filter good? Are all vacuum lines all intact? They can look OK and be cracked.
Carb tight on the intake? (careful it's easily wrapped if ovetightened).
