2005 Ford Focus 1.4 LX problems, help?

Okay, so sometimes when I drive, I have the power train warning light come on and the car then goes into limp mode.

On top of that, just before the car does get this warning light, all the other warning lights come on at once and the speedo and rev monitor along with mileage clock all stop functioning to a point I have to guess my speed and slow down.

Occasionally, the engine warning light will come on with it too. I do stop the car and let it rest for a few minutes, sometimes it works but other times it will come back on within 5 minutes.

Has anyone else experienced this? Please help?
