Hello,

I was on my way to work this morning doing 70 down the interstate when I noticed the "service engine soon" light was flashing like blinking on and off. I kept a close eye on it and after a while noticed my temerature gauge start to rise and then the "service engine light" went solid didn't blink anymore just stayed on so I pulled off a ramp and went into a gas station.

Checked out under the hood and bought coolant and filled it up. Waited a bit and started to drive again because I had to get to work and the temperature went back down to normal but my car was acting really shakey like it felt like it was rocking a bit back and forth when I wasn't driving idk how to explain it any better.

I started going through town doing 25 and it felt really weird then it goes from 25-55mph and I got upto about 35-40mph slow acceling and it didnt want to accel at all had no power then all my lights on the dash came on and the car was done i pulled off to the side of the road and shut it off. Tried to start the car back up and it wouldn't start. Tried multiple more times and it wont start. I am getting it towed a little bit later we are getting a trailer but I have no clue what could be wrong.

Any ideas on what we should look for. One person told me the serpentine belt but its fine I just had it replaced a while ago. It is a 1998 grand prix gt it has 137,000 miles on it. I've had the car since 100k miles and have never had any problems done regular maintanance on it. If anyone could point us things we should check out when we get it back to the shop i would really appreciate it thank you very much if anyone has any quick responces I can't afford to be missing work with no car .
