Aloha all who responded and read this thread!
I took it to the shop. They wanted $33.50 just to look at it and determine the problem. I was thinking that it could be in the hundreds for repair but a couple days later they called and said it was all fixed and the rest of the bill was another $35. So for a total of $70 the shop guy did what Martin and others had suggested and cleaned the rotor and it worked just great. My brother had suggested this too after I'd taken it to the shop.
Two pluses to this problem was I learned what to do the next time I leave it sit too long without use and the mechanic
gave me a new key for it. The old one had been lost
and I was using an old Mazda truck key to start and run it.
Thanks for the help and hope this will help any others who might have this problem.
