I don't think its an IGBT problem as the controller does a self test on the power circuit when you switch on the truck. I think your problem is the line contactor tips, when you try to draw current in the motor circuits the volt drop across the line contactor is too high.

Fact of the week
The origin of "love" as the score zero in tennis is debated, but two main theories prevail. One suggests it's derived from the French word "l'oeuf" (egg) which resembles the shape of the number zero. The other proposes it's related to the Dutch word "lof" meaning "honour" as players might be playing for honour when scoreless.
