95 ranger electrical problems

[Devil Truck]

My 95 ranger has being causing me problems for about 2 months now. Its a very speratic problem. I will start from the start. When it first started it wouldn't turn over. So i changed the starter. Once installed and power reconnected it worked fine for a couple of days. Then it continued to give me starting problems, i assumed low battery power (alternator).so i changed that. Work fine for a day or two, then back to hard starting problems. So i also changed the battery. Worked fine for a little bit. Then wouldn't start at all, no power to the entire vehicle. no lights, no sounds, no nothing. trimmed new battery cable wires, and cleaned up battery cable terminals to fix that. Worked fine for 2 weeks say. Then died again while trying to start... no lights, no sounds, no nothing... removed cables from connectors, and needed boost to start, but started... Worked for 3 days now and then had troubles starting again like a starter issue... needed boost to get going... I'm now scratching my head on possible issues. any suggestions on what to check or do need help...
Ive named my truck "devil truck"

I had a similar problem with my 93. Turns out the battery cable connectors were corroded and it never happened after that

I had a similar issue...turned out to be the ground cable from the battery, where it attaches down to the engine....cleaned it up well and never did any more of those things that you mentioned above
