losing power

I have a 1995 F150 4x4 302 pickup ,it runs great when gas tank is full but seems to lose power after gas gets below half a tank , is this an indication that the fuel pump is going bad or something else?

it could be but it could also be a bad fuel filter.

describe your truck a little more, mileage, when last tuned up, etc.

the plug wires need to be routed a certain way so they do not arc.

did you do this?

check fuel pressure at the rail at idle and while driving this will indicate an issue if there is one

Although we would like to see you run our Screamin' Demon Coil, a bad/weak coil is not causing your "below half a tank" loss of power. See:

this is a fuel delivery issue not ignition related. and to honest the ignition on our rigs are more then capable of handling the motors we have under the hood. keeping in tune is the key

I agree this is a fuel problem; however, I must state that even stock motors will benefit from a performance ignition(whether it ours or another reputable ignition mfg.) You are absolutely correct, that keeping in tune is a key, but so are variables such as voltage under load, dwell time, being able to run wider plug gaps, and durability.
