ChrisW70:
I think typical lift pump failure symptoms are loss of power and/or stalling, doesn't sound like your on/off description but that's not to say it has to be a definite power loss.
To check the pump, open the bleed screw on the top of the fuel filter on the bulkhead and turn the engine over - if no fuel is pushed out it definitely points towards the lift pump being suspect.
Price of a lift pump is 15 to 20 quid, part number is ERR5057 so for a few quid it may be worthwhile replacing anyway if you're gonna have the motor for some time.

topless matt:
I would have said that there is a little hole in the fuel pick up pipe in the tank.
When the fuel reaches this level, in your case 1/4 full, it starts to draw in air every now and then as the hole becomes exposed as the fuel moves about in the tank.
Id suggest getting the tank below 1/4 and seeing if the engine dies and then refuses to start, that will show if air is getting into the system in the way that i described.
