death warmed over

have a few problems. 95 tracker cold starts fine but once it's warmed up and driven a while, if i turn it off wait a few minutes, and then try to restart. she says no. Any suggestions? my othere question is, does anyone know of a computer that can read the codes for this that i can hunt down at a decent price. seems to be and aldl plug. thanks.

1995s have had a lot of problems with their ECMs. That sounds like the problem I've got with mine as well. Most auto parts stores will read it for free.
