General loss of power

[clifft]

hello all
I need some help with my ducato
I was driving along the motor way at 60 I lost power I could only go about 2000 revs
I pulled over onto the hard shoulder I stopped the engine it started fine but again after a while the power dropped off again I pulled off the motor way dropped down a gear but had no power at all
I have had it in the garage they changed the egr valve but it did not cure the problem
I have also cleaned the map sensor (I am awaiting a new sensor)
and I have not had any warning lights on the dash only after I cleaned the map sensor but that has since gone out
the ducato is a 2057 multi jet
i would appreciate any advice offered

Needs code reading, either using multi ECU scan or a garages own diagnostic
Let us know the codes it shows, and then most probably someone will know or have an idea of issue
