Ignition failure with humidity and warm engine

Hello, I’ve had a new login to the forum because I didn’t find anything in the search for my problem. I’m driving a Twingo Gordini GT for 4years with the 1.2L 75KW turbo engine!My problem started in the summer after a car laundry and a following 60km highway ride at high speed: After about 50km the motor electronics switched off on emergency program and the yellow wrench lit up for the first time. The engine lost about 50% of the line and I stopped in the next parking lot. After the visual inspection revealed nothing, I started the engine again, the Kontrll light went off and I drove the remaining kilometers with about 150km/h without problems! Two weeks later I came after longer, faster AB ride at high temperatures into a traffic jam and the problem occurred the second time! When I drove now just a few weeks ago with Niesel rain again the 60km BAB with about 130km/h, then the known problem occurred when I was driving in the Hamburg city area. For the first time the engine ran very rough and also took off bad gas! Since this day the problem started with a little bit of trouble on the ride, I’s bug, I had to look at the length of clock.
