It could be the coil is getting old. They begin to lose function when they warm up.

SOURCE: will not start when engine warm

Sounds more like your ignition module is getting hot and not working. I'd go there first before replacing the ECM. You can remove the ignition module and most NAPA stores have the ability to test them for you. Make sure they test it at least 5 times. This way it'll simulate starting and stopping.

SOURCE: 1995 pontiac bonneville stalls

I just went through lots of troubleshooting and expense on my 1996. Whenever I would lift my foot off the accelerator and was below about 30 mph, the rpm's would starts jumping around and sometimes it would stall. If I gave it a little gas (accelerator), I could sometimes keep it running. It also backfired once in a while. Starts right back up. Also, if I let it idle while in part, it would die after 1-2 minutes.

I ended up finding a hole in the fuel regulator. About a ~$70 part if you get an AC Delco, but very simple to change.

I have a 1993 dodge dakota that will not run when I put it in gear. If I let it set for awhile (2-3 hours) it will start right up and idle for as long as I want without missing but as soon as I put it into...


Check fuel filter, relay, fuel pump, sometimes the pump will run, but still too weak to run an engine at speed or underload. If fuel pressure checks out to be fine, look for a clogged catalytic converter.

Doesn't sound like an ABS problem. Seems more like a fuel or electrical problem, showing its face when you put a load on the engine, such as when you put it into Drive or Reverse
