Engine shuts off after right turns only

What is your question?

Driving along , no miss fire , plenty of gas , make any turn to the right and the engine shuts down, most of the time it starts right back up but at times it takes a couple cranks n then drives fine around left hand turns. only shuts off after a right turn. No leaks no noise, this is my baby she has over 250,000 miles but still purrs like a kitten , no valve rattle , nothing

What makes this problem better or worse?

Right turns only
