Stalls intermittently

I am not a mechanic nor do I have an OBD2 scanner. I thought that's what the mechanics did that I took the car to. They said they checked the codes with a computer.
I do not know if they checked the fuel pump pressure.
The one mechanic acted like a know it all, but found nothing. The other would really like to figure it out, but has been unsuccessful. I would like to give him some ideas to help solve this issue.

Thanks for your reply. No codes when he scanned. I talked to him about the fuel pressure and vacuum leaks. He will check next week. I'll let you know. Any idea what to expect in repair costs if it turns out to be either?

Fuel pressure okay and no vacuum leaks. Recommends to replace Idle air control valve based on past experience with a Dodge van with same issue. BTW. There are no codes because there seems to be an interruption in power, which is resetting the codes, if any. I had been having a problem of the odometer and tach not coming on right away since last year, but no one had the time to find the short, loose wire or whatever. Does IAC seem like a reasonable explanation? He feels we're at the point of trial and error because the codes keep resetting.

Had the IAC replaced. Didn't help. There were no pressure or vacuum leaks. No codes. Everything was checking out ok. But it still stalled. They then found oil in the spark plugs. Valve gasket seal was leaking. Replaced it along with plugs and wires, which crumbled as the took them out. Car stalled two weeks later. They found a small hose cracked. Fixed it. So far, so good, but it hasn't been driven much since.

Car stalled twice on acceleration up a hill. Then the third time while steady speed on level surface. But before it stalled, it bucked, tack went to zero; stepped on gas, but car wouldn't go. Still had power. Pulled to the side then it stalled. Wouldn't restart. Had it towed to mechanic. Next day it started right up and he was unable to recreate the problem. Does anyone have any other advice?

Thanks for your reply. They are checking the coil resistance right now. They said the 1997 Stratus ES model does not have a cam sensor, rather a distributor. I thought it had a cam. Please advise.

Coil resistance checks out. Cam sensor or crank sensor. Or get rid of the car.

This may or may not help but, I have a Jeep grand Cherokee 1996. And I had a similar issue which this one is a big one on these Jeeps. At first I replaced my gas cap. No solve. Then I did all plugs and wires, This one had a distributor cap replaced that and the cam and crankshaft sensor. And It started to do better then I replaced the coil thinking that was this issue. Checked all the ground wires poitive lead and batter for corrosin. Checked my fusebox and fuses inside and under the hood. All good still shut off on me sometimes, turned out to be the wires that connect the PCM computer, So find the computer on you car while someone starts it. And wiggle the connectors to the PCM and hold it in different spots if it stalls at anypoint while doing this the Sodering points inside the PCM have a break or something inside there causeing a stalling issue. Mostly More common in Jeeps and A few other Chrysler Products. But mostly Jeeps. But that may not be your issue. Just thought i'd throw my experience in here.

So what was the answer?
