i just don't get the point when the game says : Engine off

[Unisol 2.0]

while racing i'm getting the message Engine off at some points.
How do i prevent from my engine getting off?

It's part of some tracks, the "booster" pads with red Xs on them turn your engine off, it then turns back on at the next checkpoint.

Perfect answer, Schmittfeuer :)
