From the description, it's most likely an ignition problem Specifically, a failing hall effect sensor inside the distributor   Luckily, those hall effect sensors can be purchased new The distributor has to come out, and be disassembled though   Example - https://www.ebay.com.au/itm/236524819457 (however E-series hall effect plates, have the hall sensor clocked differently)   You'd need one of these, instead - https://www.ebay.com.au/itm/277224475917

for Me, 
this sounds like ignition issue, not carby/fuel related. 

but, one more test if you think it's fuel related, is remove the fuel cap (if it's creating a vacuum in the tank due to blocked hoses or fuel cap vent not working, this can be an issue)    when My XE blew it's muffler from similar, it was due to the carbon contact in the dizzy cap being worn out, check your dizzy cap inside for the center carbon (spring loaded carbon contact, if it's just the spring or nothing left, this is likely the issue )
the fact that it runs for a while, makes me believe it's the coil or ignition module or EST computer in the passenger kick panel. 
next time it stops, check how hot the coil is, if it's super hot, it's likely stuffed (can test the theory by spraying cold water on it, sometimes will make it run longer, if so... it's the coil.. 
it's not easy to test other parts of the ignition system for something that might overheat. as when it cools down, it may end up in range again. 

I have a 1988 XF carby ute manual 3 on the tree stock standard, and lately when i am driving along car just completely cuts out without warning, i can pull over and it restarts straight away then dies again not long after (time varies) but can always restart it. It idles fine, and starts fine.what can the issue be, seems to happen only once car gets up to temp.   Last time i drove it it was fine for 15mins or so then after it was at temp it hesitated for a second and backfired and blew a hole in the muffler, i kept driving and another ten minutes later it cut out completely, i pulled over and it re-started straight away, i drove another 5 mins and it cut out again, restated straight away, this went on a few times until i made it home.   I have 1/replaced fuel filter (original plastic in-line one was clean anyway) 2/replaced mechanical fuel pump 3/ checked for vacuum leaks 3/rebuilt carby   Any help would be appreciated thanks    

They work fine. Same style as Trans coolers. The Phase 4 "legend" ran a winged sump (just 2 Victa fuel tanks welded on the original sump) for extra cooling across the Mountain.

Is anybody on here running an oil cooler on there Cleveland & if so what type & is it worth it for a street car? Was looking at an XD ex cop car on marketplace place & saved a pic of the cooler & oil filter adapter & thought wonder if i should get one? TiA.   Sent from my SM-A057F using Tapatalk    

Thats awesome, appreciate the info

Swap over the reluctor/chopper wheel, and the black connector block (should plug in, where the tfi goes) not much else to it   MPI choppers have one larger gap, for injector sync (mpi's batch fire in two groups of 3) EST/CFI's are all equal gap's    

you know more about them than Me at this point.    google may dig up some useful info from other forums also, I'd only  trust fordforums.com.au only though if joining any older ones (or oldschool.co.nz but they have a very broad range of cars they cover, read the rules of the forum when joining, they don't allow posting in the project threads, they have a separate discussion thread for that, which is great for reading but difficult to catch up on an old thread if there's been suggestions and such) 

Looking at both dizzy's they appear to have the same black, green and red 3 wire setup to to module from the hall effect sensor...hmmmm

I might have a look at how the XG dizzy is wired internally and see what the difference is to the EST style dizzy is.   Externally apart from the tfi module on the side of the xg dizzy they look very similar, both are hall effect types that appear to work very similar.   I've been told to just get an XF dizzy and turn the gear upside down, but not going to go that dodgy..dont wanna leave the poor bugger stranded some where...lol   Im thinking of just getting him a streetfire and be done with it..he can work off the bill for that.
