1995 Camaro Z28, On my way to work going down the highway at approx 75mph i noticed the speedometer dropped down the 50 then went right back to 75, seconds later car completely died, lost all power, pulled over and put it in park, started it again and drove for about 30 seconds then it died again, waited a few minutes, and on the 3rd attempt i was able to make it home, local mechanic drove around and said he didn’t notice anything so there was nothing he could do for me, this is my daily driver and i cant drive a car that could just turn off at any given second, no engine lights are on, fuel pump is new, new fuel filter, battery is not dead, new starter,
