i have a 2003 f250 5.4, 110k miles, 4x4, it first happened when i was in 4x4 low in reverse trying to work my way out of a rut in some snow, it would stall, then it went away, now every once in a while it will stall out in reverse while going slow or right after i shifted it into drive and go. i did just install new outdoor marine boat speakers in the bed of the truck, i shorted the fuse out but i replaced it. it hasn't happened again i just arced the hot battery side with the negative when i was crimping the negative wire in the back of the head unit. another thing i noticed when i turn the key on and wait 5-10 seconds there is a pretty loud "bbvvrr" noise like a bad fuel pump, but other than the stalling occasionally it runs fine...maybe its just starting to go? also my gas gauge doesnt work

 

The loud noise you hear is the abs module my 2003 does the same thing as far as the other issue I dont know but someone will be along to help

 

oh cool good to know that sound is scary! wtf...
