It could be a combination - the symptoms sound like starvation - but not necessarily a sticking float. It could therefore be electrics - but electrics connected with fuel provision and not necessarily the spark. Is it an electric pump? - if so could you have a loose lead or earth that gives bad contact on cornering. I'm also on Landie electrics this weekend - much more mundane though - fitting a 12S split charger to my 2011 Defender 110. I've been so used to having twin electrics (had them on the last three Discos from new) that I never though to look when I bought the car over a year ago - specified with tow bar and electrics - first time out with the caravan in tow on this Defender and oops, warm beer on arrival in France!! With hindsight Id have fitted a new Euro plug (apparently they are waterproof) but I bought the Britpart 12 S before realising this. Just need to mount it higher than the axle!
