Did you find the problem?? My 721d just started doing the same thing..will run perfect for an hour then it starts missing and if you look at the fuel return line it doesn't have a strong flow. If you shut the mower off and start again it will run fine for another 5 min. or so.....I'm going to take off the fuel pick up tube tonight to check if there is a blockage...side note, there is less then a 1/4 tank of fuel in the 9 gallon tank.
