Already checked the battery?

Your description sounds a bit like that. A battery down on capacity can do that. Fuel pump is the first started but then it will be hard turning it over.

You stated "starter will turn it over, its getting fuel and a spark, but will not crank... "

Crank or run?

And check the full ignition wiring. When close to forests or nature sometimes Martens or Weasels love to chew the cables.
