  The behavior in magnetic fields of a highly correlated electron liquid
approaching the fermion condensation quantum phase transition from the
disordered phase is considered. We show that at sufficiently high temperatures
$T\geq T^*(x)$ the effective mass starts to depend on $T$, $M^*\propto
T^{-1/2}$. This $T^{-1/2}$ dependence of the effective mass at elevated
temperatures leads to the non-Fermi liquid behavior of the resistivity,
$\rho(T)\propto T$ and at higher temperatures $\rho(T)\propto T^{3/2}$. The
application of a magnetic field $B$ restores the common $T^2$ behavior of the
resistivity. The effective mass depends on the magnetic field, $M^*(B)\propto
B^{-2/3}$, being approximately independent of the temperature at $T\leq
T^*(B)\propto B^{4/3}$. At $T\geq T^*(B)$, the $T^{-1/2}$ dependence of the
effective mass is re-established. We demonstrate that this $B-T$ phase diagram
has a strong impact on the magnetoresistance (MR) of the highly correlated
electron liquid. The MR as a function of the temperature exhibits a transition
from the negative values of MR at $T\to 0$ to the positive values at $T\propto
B^{4/3}$. Thus, at $T\geq T^*(B)$, MR as a function of the temperature
possesses a node at $T\propto B^{4/3}$.
