Do the dials also flick around when this happens ?
If so, then it sounds like a battery problem

First, Check & clean fuses F16 & 17, who protect the instrument cluster.
Carefully prise out Mode switch while pushing it from under dash towards you and check & clean connector, jack and wiring.
If not succesful:
Depress Mileage reset button on instrument cluster for 10 secs; then step to 'button' and check readings.
If out of range, remove fascia dismount instrument cluster and clean all of its three connectors + jacks at the back. Allow 2-3 hours for job.
Replace any instrument lamps while you are at it and don't forget to buy them beforehand; there's about 10 of them in two types!
Worked in my case!

 most likely cause - battery on its way out.

If you think your battery is suspect - then your charging circuit & diodes are suspect too.
Do not just change your battery - make sure it is being properly charged - or you will end up changing it again.
