Welcome from Florida. Check your battery cable connections at both ends also for looseness and corrosion. Also make sure the alternator is charging properly.

That's a wide range of possible issues, I'll list all I've encountered.
Ignition switch control module under distributer cap faulty, injector o-rings worn, bad battery connections (did a big three upgrade to fix), bad fuel filter (or fuel pump), low battery (if it's dead long enough, it'll never take a full charge), bad ignition coil (or bad ground connection to, some models develope a loose connection) and bad ignition switch (located in cab above steering column).
Best bet, is start with cheapest issue, and work your way up.

How this helps.
