Title of post should have said "High IAT" ...... I was overheated.
About a month ago my car stalled at a traffic light, I was watching my ScanGauge and noticed when my IAT temps got to about 130 degrees my fuel pump would shut down.
It seems like my FPDM was going into thermal shut down.
I got a modified FPDM and today it happened again. This time the IAT got to 146 degrees and it happened again (at the same dam traffic light!!!). I got it home and let it idle in my hot garage and waited for the IAT to get to 146 and sure enough the fuel pump pressure went from the 50's down to the 20's and of course it died.
I believe the modified FPDM helped but not sure where to go from here.
May not be a problem when temps cool down but that isn't really a fix.
