396 won't restart once it is warmed up. I need to let it sit for a few hours before it will start again. I have a 750 Double pumper and the hose that connects to the two bowls sits about 1/2 in off the intake. Could this be causing a vapor lock situation?

Dave, is it not kicking over or just not firing up?

If not kicking over but hearing a click, the solenoid maybe getting too hot due to good old heat soak..It so, get a heat sheild for the starter.

If kicking over but not starting.

After shut down, wait about 15 min or so and check to see if there is any fuel in the carb by way of accelerator arm while looking down the throat. If none, go to tank and pull gas cap and listen for a hiss or whoosh sound.(it may help to just go to the tank first for a more dramatic sound) If you hear either, sounds like your gas cap is not breathing and causing a severe back vacuum to the tank siphoning the fuel back out of the carb. If so, change the cap.

If no hiss or whoosh sound, better check the fuel pump for some type of obstruction that isnt allowing the diaphram to seal completely, again allowing the gas to siphon back to the tank.
Also check for a strong gas smell at the carb, or does a bunch of white smoke kick out of the exhaust when you first start it up? That may be a boiled over carb from an engine running lean and getting hot.
