    MSX 140 stalls once.

    Bought a used '03 MSX 140. Each time I take it out, within the first minute the engine cuts while at cruising speed. Wait ten seconds and it restarts and runs perfect for the rest of the day. Seems electrical but have no idea what's causing this. Any ideas? Sensors?

    Any history on this machine?

    If not done already I would be changing the TPS and reinforcing the Ficht fuel pressure regulator. An old TPS can cause weird symptoms.

    Also make sure the TPS connector is free of dielectric grease on the metal contacts. Only the perimeter seal on the connector needs a thin film of dielectric grease.
