Over heating troubleshooting.

Hello I have a f350 460 engine that has been stalling on the highway on me. It dies and then 45 mins later starts right back up. Initially I switched out the ignition coil out and checked wiring. After same thing happening. I then noticed temperature rising I did a radiator flush. My coolant chamber was still getting extremely hot and all hoses leading out of the thermostat were hot. I switched out the thermostat sealed everything back up and notice a leak on back side of the housing. In process of getting the housing off I broke the dual Ported Vacuum switch so I have that coming on order in a couple days. I have already reinstalled a new housing unit and repaired the leak. I glued the broken piece of the vacuum switch together I drove it down the street a few block to put gas in it. It is still overheating and the best looks like it is building from below the housing unit and thermostat. Could this be because I have not installed the new Ported Vacuum switch? Any other troubleshooting advice will be greatly appreciated! Thanks!
