stalls?
ok stalls are complex. there are over 50 causes.
no , im no listing them..sorry.
ill not tell you to read a book, but they do tell you how to diagnose all engines. made... no kidding.
so what is it.
so the CEL did not come on as the engine SHUTS DOWN.
then that means it never fully stalled. (a key fact)
but was the throttle dead, at the SHUT DOWN? key fact 2.
if the throttle is dead, at stall.
then that is the ASD relay cutting out.
if you had scanned it at the stall it be obvious with DTC's stating that fact. in fact 8 reason there are for that.
if not asd drop this try this.
1: lost spark, never tuned up in 10 years, so spark ends.
2: lost of fuel pressure.
there is my guess, 3 things. (i skipped bad engine, (loss of compression hot)
Got P03xx codes, DTC errors. that be top of list
here is the ASD list

fixing stalls with no scan tool is like juggling blind.....
