After the engine is warmed up it starves for fuel. If I put it in neutral turn ignition off and on to run the fuel pump I can drive it home. The fuel pump does not seem to run while driving.

Bobby; >>The fuel pump does not seem to run while driving.>> That's kind of funny. If the fuel pump wasn't running, you wouldn't be driving. It is very possible that you have a plugged fuel filter. That is where I'd start looking.

As Loren said, if you haven't changed your fuel filter lately that would be a good start. If that doesn't help then you are going to have check pressure & power to the pump while the problem is happening. You don't see to many Honda fuel pumps go out. If you are having a voltage problem I would probably look at the main relay, that is one area that Honda's do have problems..........

Hey Loren,
Sorry I didn't make myself very clear. The car does run but after it warms up it doesn't have any power...no fuel to the engine. The fuel filter is brand new and the "old'' filter was also clean. Must be something besides that. Thanks for your help.

Let's give this one more try.
Sidom, the fuel filter is a new one. I will give your other two suggestions a try. Thanks.

How have you concluded that this is a fuel starvation issue?

That's what I'm thinking. The car starts up great,then I take it out for a spin and then it dies out. I turn off the key, then on to run the fuel pump then start and the car runs again until it runs out of pressure. I'm going to check the pressure while it acts up.

That's exactly what you need to do before concluding anything about fuel being the cause.
Monitor the pressure during the failure

I checked pressure while driving the car and that is not the problem. It only stalls while driving not while it is idling.
Could it be the oxygen sensor? Thanks again for your help guys.

Were you watching the pressure as the car was stalling? That's the only way you can eliminate it.

Yes I was. I had the pressure gauge on the windshield.

OK, One thing that Hondas are notorious for is the main relays failing in hot weather. It's located under the dash on the driver's side. Another possibility could be the distributor getting hot and failing from heat sink.

Doesn't the main relay control the fuel pressure? I checked the igniter and the coil and both checked out.
Thanks.

Yes, you are correct. My bad.
You really need to know if it's dropping spark, injector pulse or both. It's likely either the pick up coil or the ignitor and they are both inside the distributor so if you can try another distributor, that will tell you.

Monday I will pick-up a distributor and give that a try. It's half price at the "Pull A Part". Thanks again.

Just make sure it is complete with an Igniter.

I replaced the coil and the ignitor and tested the main relay. Still having the same problem.

First off, there is no way to test an intermittent relay.
I don't know why you changed the coil, we talked about the distributor, not the coil. It's the pick up coil that I was concerned with which is in the distributor, not the ignition coil. You were going to change the whole distributor.
