Intermittent Fuel Pump Fault

[911monty]

Fuel pump relay is likely to solve the problem. Bench test may not simulate the load. The fuel pump has minimum load when idling and goes to max load at full throttle. This is where most relays heat up and drop out. I may be opinionated due to old 911 days but a fuel pump relay was always carried as a spare. Good Luck

Thanks
Relay is cheap & replacement arrived yesterday. Will fit and see how it goes. Fingers crossed.
Intermittent faults are such a pain - each time it has stopped has been different!
3hrs into long motorway drive
2mins after starting back from a shopping trip
30mins into A road driving
Seconds after starting back after a visit to friends.
After coming back to life it can be anywhere between 50 and 500miles before it fails again.
