No crank no start

No crank no start. Replaced battery, starter, fuses, positive battery terminal all new. It shut down first time, tried jump starting no crank at all. Had it towed home then took starter off and bench tested good, reinstalled tried to start but did not crank then burnt out. Bought new starter put in no crank no start. Jumped and eventually cranked an started. Was starting up fine for two weeks then out of no where no crank no start again. Replace positive battery terminal, checked starter connections, but clicks once when turned on when turned to start one click. All lights shutoff then everything eventually does not come on or no clicks. Jumped but no crank. Going to replace battery under warranty because it discharged while connect to car since I did not disconnect. I am going to start with the new battery then go to the starter then connections as well as test with meter. It is a one click and just the engine light on. The light was on the first time is did not want to start as well. Thinking of taking it to a mechanic if I am unable to resolve.
