My car keeps breaking down. I replaced the fuel pump and Its still braking down

No it starts the first time in the morning with no issues after I run it for a bit it shuts down

main relay bad to cause problems on the acura/honda all years in the 90's and up...they have a bad solder joint on the circuit board inside the relay,had to fix mine on my 93 accord..i have one laying on my ole desk right now.this usually happens only in the HOT months..this is a very common problem on all models of acura and honda.if you google your problem,90% of what you are going to see posted is MAIN RELAY or fuel pump relay(it's all the same relay) 10% is ignition switch gremlins!.a good test when it cuts off on you and won't start back is to turn the key to ON,NOT START.watch the check engine light,when the light goes off,and it does not CLICK when it goes out,it ain't starting.then once the relay cools off it will click when the light goes off and the engine will start.google this Part Number: 20505,see what it looks like.copy and paste the link,watch the video...your relay is $50.00 plus tax at the ZONE..
