bad starter, or solenoid
sounds like your ignition module
its run on road for 5 min then rpm fluctuates and quit, seems when engine is warmed...and will not restart till cool down.
Cam and crank sensor are a common intermittent problem. try unplugging one at a time and reconnecting it. or substitute for a known good pair.subaru part number 22090aa000 application may vary contact your dealer.
MASS AIR FLOW CENSER FAULTY
if it was cold then ur engine wasnt warmed up that is one reason. or it was to hot out and ur radiator isn't working properly and it overheate. did it start after a while??
Check your ignition coil. Had the exact same problem. When it was cold, ran great. As soon as it warmed up would die just like someone turned off the key.
it expands it becomes lighter it rises thanks .!! that's all for now
what causes engine to missfire when warmed up on my 2002 accent
On my 2000 Grand Prix 3.8L the symptoms were "when warmed up a little the engine would idle up and down and then stall out, I could not restart the engine until cold" I unplugged the MAF sensor and car would run without stalling. Try this method to test yours.
The van runs well for about 6miles about 15mins. Once warmed up it splutters and stalls. I will wait for about 3 mins before the engine will re-start. The engine will run for a few more miles and will splutter and stall again.
Pistons lacking in skirts. If it continues after the engine is warmed up then you have something more severe going on.
NO, it will not damage the vehicle engine by turning the heater ON before the engine has warmed up fully.
