I have a 350 MPI Bravo 3 that loses power when cruising, the problem started after I had to jump-start the battier twice. Starts up and runs at low speeds however you start giving it fuel and it will run for about 2oo yards than loses power it doesn?t stall you just slow down pull it out of gear and wait a few seconds and it will take off again I have check the follow items.
1. Water Fuel filter took off and drained into glass jar No Water
2. Put a new in-line fuel filter on
3. Took the gas cap off to check vacuum
4. Check fuel vent for blockage no blockage
5. New fuel pump in June of 09
