Test wheel sensors >800 to 1400 ohms. /Wheel sensors>at least 0.1vac with wheel rotating at 1 revolution per second. /master valve>2 to 5 ohms measure between terminals 1 and 2 at master valve on hydraulic unit. /inlet valve>5 to 7 ohms measure inlet valve coil resistances(IFL, IFR, IR) at ABS valve block. /outlet valve 3 to 5 ohms measure outlet valve col resistances (OFL, OFR, OR)at ABS valve block /> ("?ABS pressure switch on the ABS hydraulic unit"?) <" Check the two relays>system & pump relay>fuses> the two 30 amp near the pump relay and the 10 amp fuse at the system relay for corrosion. Check the pressure bulkhead (pressure accumulator) to see if it "HOT" to touch when this happens? When mine gets "HOT" from multiple braking in short amount of time (heavy stop and go traffic)Bumper to bumper it comes on and after it cools everything is fine. I think this is normal. Don't know how you were driving? Corrosion of electrical connections? You'll have to check them all.
