Vauxhall Vivaro vivaro cuts out whilst driving

Car: Vauxhall Vivaro
Variant: 1.6 biturbo
Model Year: 2017
Categories: Electrics, ECU, Warnings & LightsEngine & DrivetrainRunning Rough, Starting & Power Loss
it's only random but whilst driving it's like engine stalls and kicks back in mainly when at 20mph+, it doesn't do it idling. The dash cuts off briefly and also I hear the relays click in glovebox, tried dashboard, ignition switch and also tested ECU and both bcm's, no warning lights stay on and no codes stored. If you try to floor it and you manage to get it to stall, the spanner light comes on and it says hill start assist not available but as you let off throttle it Carries on driving as if nothing happened and the lights go back off.

Many causes , you could load test your battery and alternator firstly before getting too involved
