Intermittent problem with sudden loss of power

From : rocdad

Q: payload on the svt has typically been less than the srt. neither have much capacity. these trucks are made for speed not hauling. heres some specs on the 04s http//www.trucktrend.com/roadtests/pickup/16304072004forddodgetruck/specificationsoverview.html this compared to the 06 1500 http//www.trucktrend.com/roadtests/pickup/16305102006dodgeram1500/specsoverview.html drager hi what difference is there between a quad cab 1500 5.7 hemi and the same truck with the v10 in it. will the srt only cope with a lighter load . a year or so ago i looked into buying a srt or a lightning. the deal at the timewas you couldnt put more than 500lbs in the bed and you couldnt tow anything. so i went for the lightning a real fun truck. this may have changed with the newer srts. roy .

i am experiencing an intermittent problem with sudden loss of power and bogging down. with my 95 ram 1500 318 sometimes at sustained freeway speeds engine suddenly loses power and runs terribly and will run only with minimum throttle and with too much throttle will backfire and possibly die after i pull over and wait five to ten minutes engine will usually run perfectly again this problem can happen after five miles or five hundred in hot or cold weather. i do not smell any gas fumes in fact i first had this problem in florida and it resolved itself then drove to california with no problem now problem is back i have replaced egr and control solenoid found it melted due to contact with exhaust system cat converter temp sender and a few other sending units checked for exhaust obstructions. i also noticed that there seems to be a vacuum in the fuel tank when the problem occurs if i loosen fuel cap i hear air rushing in past the cap the cap passed the cal smog test but i have replaced it with a new stant replacement still get vacuum or possibly pressure but it sounds like a vacuum is this normal could a vacuum be forming in the tank and causing the fuel pump to be slowed or stopped maybe that would explain the intermittent problem at freeway speeds and now just replaced evap purge solenoid but problem remains there are no trouble codes being generated. any ideas would be greatly appreciated since my girlfriend lives around 300 miles away and this could happen a couple times a trip! more i have now changed out crank sensor cam sensor rerouted wires per tsb new stock coil changed out bosch platinums with stock plugs changed out gas cap bought fuel pressure gauge pressure seems fine the problem with engine bogging down still happens after long drives at 65-70 mph i live in california and want to drive to new orleans to help victims my prevous post have not gotten any replies please respond it you have any ideas. not sure if related but since i changed out gas cap seems like moisture actually water accumulates in cap one of you guys must have an idea. .
