Your symptoms are common for failure of the brake master cylinder.  Heat in
the engine compartment apparently warps the MC enough to cause its piston
to bind.  Next time it happens, try pouring some cold water over the
MC.  The solution, of course, will be replacement of the MC, which is
relatively easy.
