Ahead of time I thank u for reading and helping me

So here the specs on my car

96 Integra LS
With a B20b swap


The car has 120k on chassis

About 60k on motor


The car drives fine but after sometime driving around especially in the heat in palm springs. My car starts to idle really low and want to die out at almost every stop.

Any suggestions on what this could be?


I had a fuel pump killswitch added about a month ago

 

Where and how is the "fuel pump kill switch" installed, on what wire, [wire color]?

Was a relay used?

What size, [amparage] is the kill switch?

Did you have this problem before the kill switch was installed?

If engine stalls, will it restart right away? 94
