    98 kawasaki 750 stx no power AFTER 30 MIN

    wth I have 1998 750 stx hasnt ran in years cleaned, tank rblt carbs, flushed water lines, replaced stator,ski will run fine for about 25 min then it seems to go into a limp mode, feels like no fuel , oil lite did come on added oil, tank reads 1/4 tank and its full bad sensor, seems like no gas or going into a limp mode, I see fuel cirulating in fuel filter
    I just disconected water temp sensor wires , when i short them together the over heat lite comes on and feels the same as in water no power
    any one have a answer is there another temp sensor some were in ecu or else ?

    also I replaced vac hose to fuel pump , and blew out fuel lines and removed petcock no blockage


    thanks guys
