Does the 1995 f150 5.0 gasoline engine model have a fuel pump driver module, and where?

What is your question?

Will be driving along fine for about 20 miles, then the engine looses power like it is going to die. Pushing gas peddle to floor and it sputters and then kicks in hard as the engine begins to excelerate again. Some times it backfires. Engine light stays on most of the time, as well as the theft signal flashing when first starting the engine.

What makes this problem better or worse?

Driving longer distances.

How long has your 1995 Ford F-150 had this problem?

Gradually getting worse over the past three months. Especially over bumpy roads
