Maytag washer timer

The washer stops during the start of the Regular cycle. If you push the button is starts again but most times shuts off again later. If you push the start button and manually turn the timer dial, you can get it to run and finish the cycle. It seems to act up only on the Regular cycle.
I’m guessing it’s the timer motor. I have looked it over and was about to purchase the timer, part 22002452. It doesn’t look too difficult, I would plan to install it myself.
Can you confirm the problem. Is it difficult to install?

Thanks.
