Make sure your battery cutoff voltage is set correctly.
Also are you talking seconds or minutes?
i believe it is set properly for the 52V battery (Samsung 35E 14S 4P), anyways, I had like an 80% charge when this was happening.
last leg coming home today, I noticed that sometimes 'motor power' would flatline at 180W or some other kind of random value, yet I could intentionally modulate my "human power" all over the place, from less than 100W to around 220 or 240W. then suddenly, I'd be getting the right pookah for the power assist level I'd set (I customized the power assist levels to just 10 rather than 20 and have it set so 4 is a good happy medium, 5 or 6 is extra boost up a hill when I'm tired, and 2 or 3 is good for the flats when I don't want to push my speed too hard. 3 gives me motor power about 2X human power, 4 is more like 3X, and 5 is more like 4X, all powers in watts, and no, I've not calibrated the torque sensor, just using the defaults there the way it came from eco-ebike, who programmed it for me.
as far as how long it misbehaves, its kinda random. sometimes its 3 or 4 or 5 full turns of the cranks, sometimes a fair bit more (10-15 full turns at maybe 60 or 75 cadence). carrying a 1L Hydraflask, and a 9 lb Kryptonite chain my pannier today, climbing the 8% grade I live up was a beating when the boost cut out. I'm not sure I can see how it could be an external wiring issue, as the display never reset, the speed and cadence and human power were always reading correctly.
