Help Please

Hello I am hoping to get some feed back and help with my 2000 Ford Focus. Earlier this week while driving all of a sudden , out of no where, my dash lights ALL came on and then the dials all jumped to the max and then fell back down and then the car died. I got a jump start from a friendly passer by started right up but then boom it happened again. I towed it to the mechanic , they did a diagnostic and stated that I needed a new alternator. I did that and it started right up , took it for a test drive and then..... 10 minutes in , it happened again????? well it is NOT the alternator :( Does anyone have any suggestions before I spend more money on tows and parts that will not fix the problem??? PLEASE HELP

Did they test the battery before they went for an alternator?

well, now we just changed the battery terminals and still the same problem?????? I just don't know where to even check next.......... I was told by a friend to try checking all ground wires....... I wonder if it is worth it ........

There should be an earth strap to the engine block somewhere. Check thats OK.

Sounds like an egr valve problem i had the same issue with my old 01 astra, at first i used to take it off and get carb cleaner and clean it. But eventually when i got money git it chagned out and was perfect
