**Need HELP 2001-interm loss of power
2001 2500 4x4 225,000 miles, 4" turbo back, FASS DDRP Pump, relocation kit back at tank, 10k ago, original VP44, no other mods, meticulously maintained
*month ago highway travel 80mph starts loosing power, like you are turning off key, stumbles regains, stumbles regains, loses power all the way to shutdown. pull of highway, wait 5 minutes, cranks, restarts- drive 100more miles at 55mph to get home.
*change fuel filters, (early), same problem
**install fuel pressure gauge, never goes below 15psi WOT. Drive truck for 2 weeks, highway trip incl without issue
* today same problem on highway, looses power, let off throttle and engine recovers, accelerate, bogs looses power, limp home this way. Fuel pressure never shows below 15 psi the whole time
I dont know what else to suspect. I have plenty of diagnostic tools...could use help from you Pro's, Thank you

and punching the throttle to the floor while it was doing this did'nt change anything...it never felt like it was in same throttle pedal position when this occurred.
