ABS failure causes loss of engine power?

[sniff_yeyo]

Pardon me If I just created the most stupid thread ever, but this is what Im concerned of:

I have ABS, DSC and brake lights yellow on my board. The interesting thing about them is that they dont come up as soon as I start a vechicle, the will come up as I reach speed of 40 km/h. then if Im going slow again lights wont go off, they stay till I restart the car, then the story repeats. Dont think it could be module, because if its faulty - it would signal from the very start( am I right?) and untill I reach my first 40 km/h ABS is working fine(tried that on the snow) My speedo is working fine, and angle-sensor thing wont help(turning steering from left to right )

Along with that I havepower loss with my X. and here what I found :

page number 18, Engine intervention.
U get the idea...

Two questions:
1. Any Ideas whats wrong with my ABS and 40 km/h thing? (pump, linings, connections, maybe module itself, sensors)
2. If the power loss is somehow in relationship with malfunctioning ABS
