I'd say transmission related. Either a sensor or the internal to the transmission. Have a local mechanic look it over for you.

And also when it does it the gauges all go to 0 and the lights flash

Check your battery cable connections. Make sure they're clean and tight. Same thing with the alternator connections. I recently had a similar issue with my '00 Grand Prix GT. The negative (-) battery cable had come loose. HTH. -Jim


I will check it out thanks for the input


You're welcome. Glad to help. - Jim


Got another question when driving down the road the temp gauge is the first big mark above 160( don't recall what it is lol) but if u idle in traffic it will reach 200 then go right back down once u take off Just put a 195 stat and bled all the air out ??


When my car cut out like yours did in the first question, it was just a clogged fuel filter.
