Wow, excellent reply. I shall have to try these things when it happens. I canceled rhe appt as the dealer didn't have any extra rental cars and I didn't want to go through it all just for the issue to not happen for them.
I definitely know it's not the solenoid as there has never been a click noise from the starter. But this issue is very similar to some of our work trucks(big rigs) and I wonder how similar the issues are. I automatically hit the brake hard when it happens in our work trucks. Have to try the car next. Thanks for the reply!
