Speedo only works for 5 mins

Hello,
Car Elan +2 1974
I'm not sure what the fix is for this but I thought you chaps might.
basically after about 5 mins the accuracy of my speedo starts to drop - when I'm doing 30mph it registers that I'm around 10mph and on the motorway I'm only doing 15mph.
The only thing I've noticed is that when I push the accelerator peddle the dial drops to almost zero and when I take my foot of the gas it starts to jump back up to around the speed I'm doing.
A previous owner has changed the speedo but this doesn't sound like a loose connection problem to me.
any ideas would be great as I'm currently using the in 4th at 2000rpm i'm doing around 30mph method to judge speed.
Cheers,
Jon
