Need urgent help with our sonata

[md11]

I have a 97 Sonata and for the past 18 months will drive along and the loose power with in the engine the radio ect will still be working and have to pull over and start the car. it may take several goes to get it going again.... The check Engine light has now started to come on as well.... It seems to be worse in cold weather as well


I have taken it to approx 8 different repaiers and still can't find what is wrong you name it we have done it put in a new computer, had the fuel pump checked and it was in the right range.

Any ideas or help would be appreaciated....

Thanks
