hi about a month ago i bout a 88 rx7 a few days after buying it i could not move past 2nd gear(into 3rd 4th 5th or rev). i had to get to work and a few other places for important things. so with riding it thru the city in 2nd for about a week lightly. she just cuts off and we push her into a gas station wait for a bout 5 mins she starts back up and we get about a mile down the road and she shuts off again. this time we wait about 10-15 min and she starts again. drives about a mile again and the engine just cuts out. thankfully by now we can just push it to the yard. and since then it hasnt been started engine wont even turn over. please help if anyone knows what i might be able to do.
