Check Fuel Filler Cap too. Sometimes they allow a vacuum in the tank to build up which would effectively reduce fuel pressure. When it loses power, pull over, loosen cap, retighten, then see if power is back....It's free so it is worth checking. Could be clogged filter on intake of fuel pump too though..
