Have you checked/changed the fuel filter?

Fuel filter was changed about 3-4 months ago.

put ascanner on it and monitor TPS

sounds like it's getting flakey

Not so sure about this, I think a fuel pressure check might be in order here. (before and after regulator)

Since you say the check engine light comes on, what codes have set? They might not be the exact cause, but will point you in the right direction

I believe the problem was the ignition module. Truck stalled and would not start. I removed the dist cap and found a loose connection at ignition module. I went for a quick drive and so far everything seems to be okay.

How many miles are on the motor? Floating Valves?
