COSMOSMotion Problems

hi, i am designing a linkage to carry data from the piston in an engine to the outside of the engine and have come into a bit of trouble. i have successfully designed my component and was trying to build a cosmosmotion model so i could predict the forces in the pivots. every time i run the model, it works fine untill around 1500 rpm where appears to change rotational direction (despite me setting it to motor clockwise) and then fail. i have included a model of the engine without the linkage and u can see, if u motor it to 2000rpm, that after around 8 seconds it changes direction. anyone have any ideas what im doing wrong, any help would be greatly apprechiated! thanks
