Sounds like a fuel pressure problem. Does it happen on both tanks?

The TB in the photos was of a TB from a 1988 E-150 5.0 AOD.

Both tanks, replaced so far all filters (oil, air, crankcase, fuel), fuel pressure regulator, and now TPS, cleaned IAC.

Problem started about 2 1/2 weeks ago, pretty much as soon as the suspension got rebuilt.

Check the fuel pressures with it off and at idle.
If the fuel is OK maybe the TFI (ICM) module or wiring.

I have nothing to test fuel pressure with, I guess thats one more tool I get to add to my. Is there anyway to test the TFI?

A lot of auto part stores will rent you a gauge for a deposit on it and then you get it back when you take it back,
They will test the TFI module for you also.

Checking fuel pressure in the morning, but after thinking about it I had a couple thoughts.

Its my understanding that when the TFI fails, it causes the truck to quit and there really isn't an in between, its either all or nothing.

A couple things I was mulling over that could be the cause: MAP sensor, engine mounts, exhaust leak/o2 sensor

Any ideas?
