2001 VX Commodore Problem after replacing fuel pump & filter

[Ben54321]

I was driving the other day got to about 80 & there was no more power in engine. I managed to make it back into town to the mechanic, turned the car off & it wouldn’t start again. He checked it out no fuel getting to engine. So I got it towed to a different mechanic who replaced fuel pump & filter. Got the car back a few days later & was fine drove 20 km return trip. On return trip stopped at the shop & drive 1 minute up the road to motel as I pulled into motel the car stalled. Started fine took it for a 3 km run out the road sitting on 100 started running rough so I pulled over & stalled again. Managed to make it back to motel & stalled 5 times trying to park out the front of room. Started car after running really rough & nearly stalling justed parked. Drove to mechanic a few days later, stalled once on way.He hooked up the computer to car that was fine. Left mechanic drove 15mins fine was sitting on 100 started running rough pulled over stalled & running rough. Had to get towed. Car has been reliable for 15 years. No warning lights coming on.
Has anyone had similar problems?
Thanks

Could be blocked fuel lines, bad injectors

Did you mark the pipes,
And place them back on the correct fitting ?

Could be a bad pump straight out of the box. There is no quality control anymore. The end user is the quality control.
