Classic Speedo possible rollback

Hi

When I start my DMC it runs fine, but if its been running for about a 
minute and i push the throttle down it hesitates and looses power 
then when the engine has warmed up its fine again. Any ideas

Also the speedo works fine but both the trip and milage counters do 
not work. I checked the Lambda clock which said 74 and i have done 
around 150 miles since and still says 74, but a unit is obviously 300 
miles.

Any ideas 

Thanks

I hate to be the Bearer of Bad News,but it sounds like someone has 
played around with the mileage odometer(rollback)usually when the 
speedo works fine,and the odometer,doesn't,it means that someone 
pulled the odometer out of the case and physically turned back the 
odometer,and did not reinstall it correctly,or used picks to turn it 
back,and screwed up (broke/screwed it up)the connection between both 
odometers,I had one car (a GM)that came from a rental company that 
the speedo worked fine for a long time(about 10yrs) then all of a 
sudden the speedo would turn 10,000 miles for every 100 miles I drove 
it,took it apart and found out that it had been tampered with
(rollback).
