loss of power for a second

[gbkeyman]

car runs fine....just three times in past two weeks or so .......i hit a bump and it has no power.....just for a second....i look at afr gauge and it says no fuel......when i log i notice the fuel trims have reset to 100.....i think my power to ecm is being stopped at times....or is this a capacitor issue....my ecm looks to have been repaired for this problem but i do not rule out as a cause. any thoughts would be appreciated...

This is often due to the battery not being bolted down (and positive terminal w/o rubber insulator on) and shorting against hood or strut tower bar.

If that's the issue, get it fixed ASAP. Can cause fires.

thank you for the idea....had me goin . batt is down tight, and proper size. so it is not close to hood...and has cover on pos term and no sign of arcin to anything. checked terminals and connections to ground and pos best i could. when it dies no other electrical problems present lights on and brite. just no power. did tap on ecm when running and no problems. did notice footwell lites off and if i move fuse block they come on and off with pressure. but car does not stutter it runs fine with lite on or off when door open dont think they are related. but u never know......will keep lookin

this problem was resolved with a slight twist to the blade of the fuse for footwell lites etc... had a spade female open slightly and lose contact apply pressure to fuse lites come on with good contact no more problems
