    Yea, that won't help if you had read his post.

    Are you getting spark? Sounds like is actually flooded and the 45 min is the gas evaporating. Could be a sticking needle and seat.

    Pull the plugs when it won't start and see if they are wet with fuel and check for good spark. Check your stop start switch for sticking as well.

    Odd for sure.

    Sounds familiar, weak spark?
