Not enough information.
Assuming you've ID'd yourself as an officer, and assuming you've got probable cause, I'd tase if he refused to stop, falling back on US v Dotson, which states:

Now, I believe a taser is "reasonable" here, since he's fleeing, it's not lethal, he's not obeying my commands to stop, and a fist fight probably wouldn't end well for either.
In a parking lot, assuming the absence of a huge crowd who may experience wind contamination, OC would be a viable option as well.
