engine cuts out at high revs, eml on td5

hello all, whilst driving my defender 90 td5 along the motorway trying to reach 70mph, my engine would cut out and the eml would light up. i have had this problem for ages and have spent a hefty amount of money trying to solve it however i still cant seem the crack down on the issue

Things i have done:
new injectors (as apparently the old ones failed the test)
new startermotor
new fuel pump
new genuine crank sensor and spacer(ran a new loom from the ecu plug to cps just incase the wiring loom was knackered)
new fuel temp sensor
new boost hoses(however was quite a bit of oil in it so a new turbo might be the next thing to purchase)
new fuel filter, air filter, cleaned map, maf
made sure that the wastegate valve was not stuck(will test pressure on it with compressor soon)
all earths have been extensively cleaned
new injector loom, also checking for oil creep in the plug
new fuel filter valve

i suppose with the help of a nanocom, i could see if it was boosting properly. if so what would the correct pressure be?

Any help will be much appreciated

So you wait a bit and then it goes again? if so likely an ecu issue, common enough.

Was a spacer fitted to the old crank Sensor?
Set Boost pressure with Nanocom to 1.2bar max.
