I run a mail route and at or about halfway, (about 2 hours of running and a lot of start and stops) my engine starts to decrease in speed and run rough and if I try to excellerate there's no response and then, it will "catch up" and throw me back against the seat for just a second, and then no response. It just repeats this cycle until finally, it will die and then start but not stay running.
