Sounds like a clogged fuel filter to me -- or something else causing fuel starvation.  Initially it started out messing up the idle, then worsened to where there's not enough fuel to let the engine rev

Check for a pinched or improperly routed fuel line in your 86.  Petcock control ? Someone with an 86 can elaborate.
