Random Shutting off on 98 Suburban
Been awhile since I have posted here in other threads. I have been beating my brains in on this problem. Read alot of things...watched a few videos and googled till I couldnt reword the problem any other way. This 98 Suburban with 5.7 would just shut off at anytime, anywhere and any distance. Sometimes it would shut down after a mile or two or shut down 20 miles away. Shut down while moving or sitting at a stop light. When it would shut down, turn the key back to off and then it would restart. If you tried to start it without going back to off, then it would just crank over. No start. Tried telling my wife this, but, she just kept turning the key till she destroyed the flywheel, starter and broke the outer starter bolt hole on the block. Dont ask me how she did this. Never seen that happen before on a Chevy block. At 256,000 I would say its done its job and I got another 5.7 to go in. I am in the process of putting the engine in. But, back to the issue. Anyone else had this random shutting off? We can rule out the fuel pump. I thought that was it. Tank, pump and pressure sensor is all new. Complete tune up. All the battery cables and battery has been replaced. Even the cable going over to the fuse box. The only code I had was misfire. So I did the tune up. Replaced the coil and module. Lots of new parts have been put on since I got this thing. Including cam and crank sensors. So you can see why it is driving me crazy. (Wife didnt help things either.)
Any and all input will be appreciated.

Re: Random Shutting off on 98 Suburban
Considering the mileage on it, I am thinking ignition switch or the neutral safety switch is worn out or flakey. Other than that, I can't think of what to trouble shoot.

Re: Random Shutting off on 98 Suburban
Did you do the relearn after the crank sensor?
