Hello,
My Brother's 98 Marquis has stared to experience a power loss when driving on the highway. The problem occurs every 90 minutes; so he is pulling over and letting the car cool down. On one occassion he tried to put the 4-way flashers on when he could not keep the car going 55mph on the interstate and the 4-way flashers would not come on. He tried them again after the car had cooled a bit and they worked.
I think the battery in the car is original. The car had sat for 3 weeks in a garage before this problem occured.
Any ideas or similar experiences? All input is always greatly appreciated
Thanks
