is that the same sort of problems you had
Massive delayed reply but yes that sounded like how mine was.
Problem is there seems a few things that fix this.
I changed the spark coil and the car was fixed for half a year but then it came back. Changed the fuel pump and it was still iffy, turned out it was the fuel pump sender (or the module what ever its called) the second time.
Both problems only caused issues when the car was warm
