Default Loss of power in T5 on bumps


I have a 2010 vw t5 LWB 2.0 todo 182k
Had timing belt changed
EGR valve changed
Water pump
Serviced regular

Wondering if anyone could give me some info, when I'm driving & go over a bump or the brow of a hill the engine acceleration will drop until I take my foot off the accerlator then put it back on and the van will accelerate I'm not driving over the brow of the hill like the dukes of hazard.... ha

Is this normal & or could it be related to :
There is a yellow flashing light on the dashboard ( engine glow plug) when I accelerate I've taken it into the garage & he put it on the computer & it showed crankshaft or crank case sensor & awaiting for the weekend for it to be fitted,

Any help would be great !

Many thanks Jamie

Mine seems to hold back a bit when going downhill, no loss of power or any issues with warning lights on, so i just assume it's something to do with the stability control? As an off-road driving instructor this doesn't bother me as it allows a controlled descent.
