Unhappy 73 450SL purrs then runs rough after 5-10 min

What would make this 73 450SL run fine on start up but then after 10 min start missing and running rough? I have changed the coolent temp and aux air, checked out the MPS and the plugs are not fouled, it is like the amount of gas or air is changing. What would be a logical troubleshooting procedure for this problem, all the vacuums have been checked and verified with a vacuum guage
Thanks In Advance
