So, I bought a '65 V8 289 Mustang that is a bit rough around the edges, but in good condition. The engine's very clean, and was rebuilt but it wasn't the best job ever. Some of the parts are going out. I believe my problem lies in the Starter Coil,

The engine will begin to lightly surge after driving for about 20~30 minutes, the more you drive it the more noticeable the surging becomes. Eventually the car just stops. The engine cuts out, and refuses to turn over, and the more you try it drains the battery, giving you a dead battery. My first thought was the Alternator, but my dad suggests it's the coil. He says they go out like no tomorrow on mustangs of that year.

So my question is, is the coil a safe bet, and is there some way i can stop this from happening??

It is definitely a vapor lock problem. Today's unleaded gas is much more volatile than the leaded gas of the sixties. The fuel line on the '65-'66 Mustangs runs on the inside of the sub frame rails, only inches away from the hot exhaust pipe. A heat shield will have to be fabricated, or the fuel line will have to be relocated. I experienced the same problem on my '66 many years ago. I relocated the fuel line to the outside of the frame rail, and it never did it again.

Starter Coil??? do you mean starter solenoid? what would the starter have to do with it when the engine is already running? I'll assume you meant ignition coil. Yes, a faulty one of these can cause your car to die. However, you said it refuses to "turn over". If the engine will not turn over when trying to start it, it could be a starter problem but that wouldn't cause both your issues. depending on how the engine runs (good, bad, milky oil?, etc) it could possibly be a bad ignition coil. Replace it and go from there.

on older mustang they have point & rotor in the distributor .your points could be bad are they need to be gap & your timing needs to be check. if coil was bad you wouldn't be getting any spark at all.if you replace the points don't forget to replace the condenser.
