Range Rover Vogue SOMETIMES WONT START

I had that on my 52 plate a few years back. We were abroad, going from Holland to Belgium, car running fine, stopped on motorway services, car refused to re-start. It would crank quite happily but no start. Recovered to main dealer who ended up changing a fuel pupm at the back end. That sorted it for a while, then same thing happened back in the UK, my indy garage found it was the other fuel pump under the back seat causing the non-start. That car cost me more in repairs that it cost me to buy from new.
