inherited 68 cuda, starting issues

Fuseable link?
Not sure? I'm pretty new to the engines of these cars. My orange cuda I bought built and sold in under 3 years. Never really had time to get to know them. No electronic ignition.. pretty much stock 383 with some exceptions. Got it to turn over, fire and run for about 30 seconds. Hopefully its just the old gas burning out.. hoping to get it started and idled here tomorrow. Every time I try and rev it up it will die. Get it to start and almost idle, feed it gas but dies. The woes of having it sit for so long I'm hoping.
