Boat ran fine then stalled cranked and started and stalls again when forward engaged. Did this a few times then would not start. Took it to Mercury dealer, bad alternator. Repaired along with fuel tune, lower units serviced and all fuel systems checked and pressure tested. Put in water and ran it up to 4000rpms, then ran it to 4500 and then up to 5500. Backed it down after 40 seconds at 5500 to 3800 for 10 minutes then to an idle. The port motor stalled and did the same thing, start then stall into forward. It now will idle but anything over 1000rpms she stalls out. Pulled it and back to dealer. Again all system checked along with voltage in the NEW batteries and throttle position sensor. Fuel pressures again checked and all in spec. Air compressor fuel mixture etc e t c. Nothing on alas or computer comes up with any codes. Dealer has called Mercury and what they suggest has all been done. Anyone else have anything similar as we are stumped
