You gotta give more details because this could be fuel related or poor electrical connection getting worse.
When this happens and you restart, does the engine rev to any rpm? Does the bogging occur at any rpm? Are you getting any codes?
When it happens, don't pull over - instead, pull the clutch in and hit 'Starter' button, and see if it restarts, then gently rev her up while releasing the clutch. If after that you can stay in lower gear and get revs pretty high and nothing happens, I'd say it's not fuel related. However, if it consistently bogs down as you try to increase rpm, then it's fuel related.
Let us know...
