I used to get similar lift pump supply voltage issues on my old 306 - issue was that one of the high-current terminals on the relay socket itself had got very hot to the point that it was black, and randomly it would result in a lousy connection, low-voltage at the pump and a non-start.
Simply removing and reseating the relay would fix it 9 times out of 10 and the car would then usually go months without missing a beat, only to randomly fail to start again one day. Never cut out once it had started though in the 100k miles I owned it.
Looking at the mountain of history that came with the car it had numerous relays and lift pumps fitted to try and fix the resulting symptoms, but evidentially the (mostly Peugeot dealer) mechanics had never spotted the relay socket itself was the underlying issue.
