Stalling on high speed right turns only???
 

My 83 300d is stalling/losing power on right turns only, even with full tank. Could it be an airleak..sucking air some where or fuel starvation?? Thanks..I know this is probably a redundant question..But this is the place to get the answer.

This is just a stab in the dark, but I would be more inclined to look at the electrical connection to the shut off valve. What could be happening is, that when you make a right hand turn at high speeds, either the engine shifts a little, or something else is causing the shutoff valve connection to be d-activated, which will cause the engine to stall. Good luck!
