eml and check engine lights on car in limp mode any suggestions?

[BRUMMIE DAVE]

car starts fine from cold with just the check engine light on drives fine nice and smooth but turn off the ignition and re start the car and not only the check engine light comes on but also the eml light and the car goes into limp mode have changed the two sensors that were showing on the diagnostic computer but the problem persists and any  help would be much appreciated.

First thing is check the battery. Mine did the same and randomly put the car in limp mode.
