Sputter, hesitate on acceleration and die

[IamJerry]

My 1994 F150 will start out fine. Intermittently, few hours later it will sputter, lose power, hesitate on acceleration and eventually die. I can switch tanks and it will jerk and go a little further. If I let it the engine cool down it will start up and I can get on my way, sometimes with no further problem. The tanks are at least 1/4 full. Operating temp is normal. It can't be the fuel pump because it happens in either tank. I have no ignition module on the distributor (Like my older F150). I am told it is likely the ignition module, but I don't know where it is. The book is no help how about you guys? Any other suggestions? Thanks Jerry

it's on the inside of the left fender, top on the back side of the wheel well.
