Problems with Astra 1.8 2004

After making body washing and motor. The car has been left with a fault.
I explain. I don't know if you have to do but it went to root from that.
The vehicle lights normal. And it accelerates normal but after a few minutes of ignition it goes out suddenly and the motor and key lights begin to stand several times. After that does not turn on until about 5 minutes without the key.
Then I turn on again and the same thing happens. But if I keep the car accelerated to more than 2000 rpm it does not turn off. When under -1000 it is stable for a few minutes and goes out sharply. Can anyone give me a sign that it can be?
Clean the contacts of the cables with contact cleaner, take the alternator to prevention maintenance, change the spark plugs and remain the same.
Here is a video

What I see there is the Check Pilot on, a signal of a sensor, some connector that was not well sealed and has entered water or taking moisture, you should bring a scann to see what code it tells you, or check the connectors and box of relays/fuses in the motor compartment, greetings !!

It is true what you should worry most is the light of check lit, the party hose of the MAP or the multiple Checalas may be alleged or loosen
