06 dash dies and power cut/surge

my boss has a 2006 f350 regular cab. quite awhile ago driving it one day the dash gauges all went dead, the radio went dead along with display lights, and the power windows dont work. the dash backlight stays on but gauges and warning lights dont work. check engine light is on but it was a code that never got cleared from a service... and a code for a bad fuel level sensor and a power cut code??? dash would die randomly no reason and would come back on within minutes usually.. sometimes longer. and i never noticed it causing any other problems.. then i was driving with him and he would stay steady on the gas but every 3 seconds or so it would lose power for a second then go back to normal.. didnt matter how hard he pushed the pedal it would cut probabaly the same percent of throttle every few seconds... wierd and really annoying to drive like that.. the mechanic had a theory that the bad fuel sensor could be tied to all of this mainly the power cut possibly in an attempt to save fuel because it thinks its low?? anyone ever heard of this?

sounds like you have 3 seperate issues. The radio, power windows and cluster issue I would suspect is the cluster itself as the battery saver relay which indirectly powers the radio and power windows is internal to the cluster. The fuel level sender codes will not affect the way the truck runs, just turns the check engine light on and can make the fuel guage act up. As for your intermitant cuts out gonna need more information

so the dash/radio/power windows on a relay that can get changed easily or ur saying its internal somewhere and everything would have to come apart to fix it? and yes the low fuel sensor makes the gauge read empty sometimes when its not thats not really a big deal.. if it ever happens to me i could get a little more specific but ive only been in the passanger seat so far when it did it. from what my boss says it only happens when the dash and radio are dead and he says it doesnt seem to matter if it's warm or cold. lets say hes giving it 1/4 throttle.. it feels like 1/4 throttle for a few seconds then then all of a sudden it feels like he lets off to 1/8 throttle but he never moves the pedal.. its almost like it doesnt know the throttle position for a sec or 2 the rpms lower on there own like hes giving it less throttle but hes not the trucks doing it by itself. its weird never seen anything like it before. it just kept going normal throttle then dropping then normal then it would drop.. it was consistant too not sparatic like all over the place. it seemed like when it dropped it was about half of what throttle he was actually giving it.. like if he had half throttle it would stay half throttle for like 3 seconds then drop to 1/4 for a second then go back to half throttle for 3 seconds and so on.. full throttle for 3 seconds dropped to half or 3/4 throttle for a second then back to full throttle. not running rough or studdering or missing just seems like the throttle position is all effed up. for the 9 months or so the dash has been dying thats the first time ive ever seen it run like that with it out so its not very often.. idk if it makes a diff but it is a farm truck.. hooked to a gooseneck 75% of the time pedal to the metal ahahah. just hit 100,000 miles interior is far from clean the panel under the steering wheel is halfway falling off idk if dirty/dusty connections in there could cause any of this?
