update: ignition control module has been changed and I have moved the wire harness around with the car running and it still cuts out like it did before.

if it cuts out when you move the wires they are bad or there is a loose pin in one or a few connectors

I should of said it did not stall out when moveing the wires around but it does still stall out when driving or sitting at a light

Today I hooked up the scan tool and also checked the fuel pressure at the regulator:

One code was P0102
MAF or VAF circuit low input
Engine off MAF was at .22 lbs
Idle in gear at 660rpm .53 lbs

Fuel pressure 44psi with engine running, would slowly rise to 53 when shut off

o2 sensor #1 voltage was all over at .01 to .8
o2 sensor #2 was a steady .555 and changed with tps change

If anyone wants a Bonneville, I might be getting rid of this one soon if I cant get it running right. Its my main transportation and I cant trust it for long trips now.

Did I suggest to disconnect the MAF sensor and see if it will still cut out?

Are you using junk yard parts .. crankshaft sensor/ICM?.. most of the electrical parts in the junk yard have failed causing owner to just junk car

For the car to just die as running down the road, would seem to be a heat induced issue, like the cps or icm...are failing when the heat builds

are the parts new or used?

it stalls or cuts out when driving even at various rpm'*. at a light it will stall out and will restart right away.

Sounds like a loose wire or corrosion .. Ground Wire?
