If your battery is fully charged then you have a bad connection between the battery and the controller.
The only other thing could be a completely bad battery.

Agree with spruce
Go through your wiring esp rather connections we recently had batt problems the earth wire had broken inside the batt terminal clamp it still made a connection but effected the charging new terminal and all is good

Hi The controller has a built in volt meter and is regularly checking the battery condition. Depending on the age of the battery it may not be holding a charge very well.
The Controller will warn once voltage reaches 11V while under load from the pump and at 10.5V the controller will stop the pump to prevent damage to the battery cells.
Most leisure batteries can be discharged to 50% of capacity and if the battery is at around 11V it has reached the 50 % discharge point. A sign of a worn battery is that it show low voltage after about 30 minutes use and the volts fall way suddenly. A good condition battery will gradually fall off over about 4 - 6 hours
Out of interest how old is the battery ? and how often is it bench charged with a mains charger
The Controller does have a low battery cut off over ride, Please be aware that if the battery condition is poor that the pump will simply exhaust the battery to a point where it is unusable

This is a good link covering the discharge and recharge cycle of a Leisure battery.

Battery was 3 months old when the problem started one minute it would say it was 7.9volts next it would say 12.9

Try running it off your van battery. This will tell you if the battery is the problem.
A battery can develop a short inside but can still show a full voltage. Under the slightest load it will break down to the low voltage you mention.

Ok cheers for that guys 🙂👍
