You'll come out farther ahead in the long run spending money on tools and know-how you can keep, than on a bunch of new parts you give away in frustration.
In this case, you're the only person who can fix this. You need to pay attention to the car, though. How does the car feel when it dies? Does it sputter and chug, lose power and die slowly? If so, then that might point to a fuel delivery issue, like a malfunctioning injector. That might recall to mind that fresh gas smell you notice every time you turn off the car, for example, which would confirm your fuel delivery suspicions. It could also point to an ignition issue like a wire getting hot and losing connection. That might remind you of that crusty wire in your engine bay you've been ignoring, as another example.
If it dies real clean, like someone simply turned the key off, then that might point to something like a bad ignition switch. That might remind you of the heavy keychain the previous owner had.
The point is, there aren't easy answers on a 35 year old car. Only you know your car, only you can listen to what it is telling you, and only you can connect the dots. Tools, manuals and diagnostic aids will help you, but you have to do the detective work yourself.
