AUII cutting out

[Bossxr8]

My AUII wagon has been cutting out intermitantly, especially on hot days. You'll be driving along and it will just drop revs, not respond to any throttle input and eventually run rough dropping to 200 or so revs and then die. Give it a few minutes and it will start after a few attempts and then run fine for a while and then sometimes do it again. Buggered if I know where to start. Its pretty random, runs perfect for days on end then starts doing it.

Fuel pump seems to be noisey but if it was stuffed wouldn't it just die and not restart again.

Or maybe fuel filter blockage? Wouldn't explain why it happens mostly on hot days.

Electrical/sensor maybe?

Anyone help.

[Mr Hardware]

i was going to guess fuel delivery in some way, as you say especially on hot days. Just remember when you restart you prime the lines again so that may give it enough to keep going for a while. Perhaps there's some leak in the lines?

Would a fuel pump intermitantly fail, or would it be a case of once it goes thats it?

Can fuel pumps overheat? My missus never runs more than half a tank in it stupidly enough.

[Mr Hardware]

Any mechanical or electrical component can intermittently fail.
Try running a full tank. I know in the hazy days of my past life in a mechanic's workshop people with fuel pump faults would often say it wasn't so bad when their tank was full or near full.
