It started where i could drive it for about 10 minutes then it would lose power and shut off. Later that day, I figure drive it to a local shop, now it runs rough and would only run for about 30 seconds and shut off. (multiple misfire code).
The shop has looked at it but they are stumped.
I'm starting to lose faith in the shop as they have been looking for 4 days now.

Good morning,

I agree. You need to find another shop with more experienced technicians.

I would check the fuel pressure to be sure the fuel pump is working correctly.

I would also have the spark checked as well.
