7.3 Wont Start, Maybe Seized?

I have a 92 7.3 IDI obviously. It wont start and I have no clue why. It has never given me a problem before then this happened in two days. I was at the store and I got in the truck. Primed the plugs. Turned her over and nothing. She kept turning over and then would slow down. As if she was trying to overcome something (maybe stuck or sticking? Idk) then turn over at normal speed. Tried a little ether (which didnt help) eventually she coughed to life. Drove her home no problem. No noises etc. Next morning. Went out. She coughed right to life. Ran some errands. Killed and started the engine several times. She started fine everytime. Came out of my last store and she did the same thing as yesterday. Except finally, she wouldst start at all. If you turn the key to 'start' you get one loud click and that's it. I want to say its the starter but Ive heard that maybe its a seized alternator. Im hoping its not my engine but Im lost and dont have the money to just start replacing parts. Any and all help would be appreciated. And of course by laws of life this was a few days before the truck was about to go on criaglist.

check resistance in your batt. cables.

Had an 88idi, bout the same symtoms. 2 new batteries, new starter ( pos stud kept backing out ), wound up being the battery cables were ate up with corrosion.

This is going to sound extremely novice sounding but how the hell do I do that?

Start off by taking the belt off and turning everything by hand to make sure nothing's stuck. The take a breaker bar and a socket and put it on the crankshaft pulley and make sure it isn't siezed. Then do the steps listed above.
