I have the same problem as you, mine started about 6 months ago first just a hiccup not a complete stall every now and then. Now I cant even drive it down the street without it stalling. The mechanic I take it to as yet hasn't figured it out as when I take it back it seems to be running perfectly [ only stalled once for him ] The last time I left him I took it for a long drive about a 100 Ks no problem a couple of hours later went to take the dog for a walk problem back. Taking it back on Monday. Let me know how you go and visa versa.
