If you have points in the distributor then they wear out and the timing gets off. I think you have electronic ignition but if the bolt that hold the distributor in place is loose then the timing can get off. The timing should be set around 10 degrees before TDC. If you are setting it by ear then that is probably your problem.

the rotor in the dist is off not the case...out side hold down bolt snug and is set @ 10* why does the rotor get out of cycle?

Check the mounting of the rotor. If it is damaged then it can slip. Try turning the rotor by hand and see what happens.

Take and grab the rotor and try to see if it will turn the shaft. A common problem is that the roll pin that holds the distributor shaft gear on shears. All you have to do is pull the distributor and replace the pin.
