Hello all,

I have a 95 Chevy Suburban c1500 I have recently updated pretty much everything for the drivetrain and engine.Vehicle has 248,000 mi The motor runs excellently but for some reason it randomly stalls and dies doesn't matter if I'm in drive or at idle.All sensors have been replaced which include map sensor CIP sensor EGR sensor you name it everything. I have a brand new TBI system. New spark plugs wires distributor. New fuel system including fuel lines fuel filter fuel pump ..everything literally everything. I can't for the life of me figure out why it randomly stalls I've recently discovered that the ground wires are a little bit rotted so I'm going to go ahead and change those and hope for the best. I've checked everywhere that I could possibly check for any type of air leaks fuel leaks etc. any type of advice would be absolutely wonderful. I'm literally running out of things to change. I look forward to All of the responses. Best regards, Kyle

Does it happen in at driving speeds or only at a stop?

Kirklander

All different speeds

And stops Even in park a randomly shuts off sometimes

Rednucleus

Does it stop like whenyou turn the key off, or die like struggling for fuel?

Kirklander

No not at all but when it does stall I noticed that the RPM's needle starts to shake rapidly and when I'm looking under the hood where the TBI is it's buzzing so I'm starting to think that it's a ECM issue

It just straight dies randomly it's almost like it's a ground issue but I'm really starting to think it's an ECM issue
