    HI
    briggs vanguard 16hp ohv vtwin correct
    The issue is either fuel or spark .
    First u need to determine if the argo body electrics are earthing[killing the spark] or the actual engine electrics [plugs ,coils ,2x diodes]
    Disconnect the kill wire [located on the fan cover ] engine will not turn off by the key .
    If engine electrics use a coil tester to check coil spark
    The diode wire may cause intermitant problems but is easy enough to change .[behind fan cover ]
    If u suspect fuel system flush /clean tank out ,replace lines ,replace fuel filter ,cleanout carburetor
    NB there are genuine PDF manuals on this site in the engine section
    The carburetor fuel cut off solenoid may be causing this

        I would guess it's the magnetron, assuming it's the opposed 16 I/C twin.
