my car has been losing power and having trouble starting acting as if out of gas on 2012 Chevrolet Malibu

I took to Chevy dealer they could not find anything wrong. After a week they I pick my car back up from dealer and made a stop , when I went to start the car back up , it would not start. After 39 minutes It finally did start , just as tow truck came to tow. No one can find out what is wrong . PLEASE any help would be so appreciated . I am single parent and am concerned to go out on highway , or anywhere until I can get problem fixed.

you should have all data recorded on your car at that point it can be downloaded and reviewed frame by frame to pinpoint the issue
The fuel pump and filter is the common problem on those with that symptom, Proven and verified.
the Chevy dealership is telling me they can not find anything wrong . When they put on machine will the results show that this is the problem? And thank you
The machine will not show the fuel pump. Honestly a fuel pressure gauge will need to be use band the car duplicate the fault to be able to see it.
THANK YOU I WILL CALL DEALERSHIP IN MORNING.
U Bet let me know.
I had the same problem with my 2006 Malibu. Even had a zone manger look at it. Ended up taking it to a small mechanic who repaired it for $80. I cant remember the part he replaced but please don't spend your money with all of the trouble shooting.
